Question

The graph shows the number of particles with a given kinetic energy.

Answer 1

How will adding an enzyme change this graph?

The curved line will shift to the right.
The curved line will shift to the left.
The activation energy line will shift to the right.
The activation energy line will shift to the left.

Answer 3

a?

Answer 4

An enzyme is a biological catalyst that is used to decrease the amount of energy needed for the reaction to occur

Answer 5

so c?

Answer 6

Answer 7

I feel like this question is written a little funny, I think it might actually be B, if anything moves right it shows more energy since that's what is open the x axis if the graph shifted left then it would show that less energy was needed so I'm thinking it could be B @JoannaBlackwelder can you please double check this I don't want to give a wrong answer!!

Answer 8

A chemical reaction is shown on a Maxwell-Boltzmann graph. What information is displayed?

The activation energy required for a reaction to begin
The distribution of particles with enough energy to react
The half-life for the concentration of reactant particles
The relationship of temperature and pressure in a reaction

Answer 9

@taramgrant0543664 a?

Answer 10

I'm thinking that one is B

Answer 11

A scientist monitors the reaction between two gases in a closed container. What would happen to the rate of the reaction if the scientist increases the temperature in the container?

The rate would increase because higher temperature would increase the number of collisions.
The rate would decrease because the particles are unable to achieve the correct orientation.
The rate would decrease because the space available for the reactions would decrease.
The rate would increase because the average speed of the reactant particles would decrease.

Answer 12

d?

Answer 13

@taramgrant0543664

Answer 14

That one I'm pretty sure is A an increase in temperature gets the atoms move faster generating more collisions

Answer 15

What procedure could you use to test the effect of a catalyst on a reaction?

Add the catalyst to the reactants and then increase the temperature until the reaction occurs.
Combine the reactants and the catalyst to see how long it takes them to react.
Combine the reactants; when they begin to react, add the catalyst to stop the reaction.
Observe the rate of the reaction and then observe it again with the catalyst included.

Answer 16

c? @taramgrant0543664

Answer 17

In order to test the effect on anything you need your experiment and your control the experiment you would see how the catalyst changes the reaction and the control you would not put the catalyst in so D would be my answer

Answer 18

Zinc reacts with excess hydrochloric acid to produce zinc chloride and hydrogen gas. What happens to the reaction rate if you increase the concentration of zinc?

The reaction rate decreases because the area available for particle movement is decreased.
The reaction rate decreases because the probability the reverse reaction is more likely.
The reaction rate increases because the energy of each particle increases.
The reaction rate increases because the probability of collisions increases.

Answer 19

a? @taramgrant0543664

Answer 20

The reaction rate would not decrease if there was more zinc it would increase because more collisions occur

Answer 21

so d? @taramgrant0543664

Answer 22

That's what I was thinking

Answer 23

Why does increasing the temperature of a reaction cause the reaction rate to increase?

The potential energy of each particle increases.
Increased energy enables more particles to collide.
More collisions occur because average particle speed decreases.
The average kinetic energy of the particles decreases.

Answer 24

b? @taramgrant0543664

Answer 25

B sounds good to me

Answer 26

all was right :)

Answer 27

even that enzyme one?

Answer 28

expecpt for this one

Answer 29

The graph shows the number of particles with a given kinetic energy.

Answer 30

How will adding an enzyme change this graph?

The curved line will shift to the right.
The curved line will shift to the left.
The activation energy line will shift to the right.
The activation energy line will shift to the left.

Answer 31

it wasnt b

Answer 32

ive never really did anything with those graphs before like I've heard of them but never studied them

Answer 33

oh ok @JoannaBlackwelder you kno the answer than?

Answer 34

this was tricky

Answer 35

It is tricky I know that the activation energy decreases but the way it's all worded I'm not a fan

Answer 36

true lol

Answer 37

http://www.chemguide.co.uk/physical/basicrates/catalyst.html This explains it kind of

Answer 38

So from the link I'm thinking it should be D

Answer 39

ok ima try

Answer 40

it was coreect :)

Answer 41

Yay!!!!!
