Question

If an endothermic reaction is in Equilibrium, What will happen when you increase the temp? (1 point)
a. More reactants form
b. more products form
c. no change in the amounts of products and reactants occur
d. the system does not reach equilibrium again

Answer 1

Have you heard of Le Chatelier's Principle: If a dynamic equilibrium is disturbed by changing the conditions, the position of equilibrium moves to counteract the change.

Answer 2

No

Answer 3

In an endothermic reaction, if you increase the temp., more products will form

Answer 4

Well according to Le Chatelier, the position of equilibrium will move in such a way as to counteract the change. That means that the position of equilibrium will move so that the temperature is reduced again.

Suppose the system is in equilibrium at 300°C, and you increase the temperature to 500°C. How can the reaction counteract the change you have made? How can it cool itself down again?

Answer 5

To cool down, it needs to absorb the extra heat that you have just put in and a reaction that absorbs heat is...? Endothermic. So increases in temperature favor the reaction direction that consumes heat, while decreases in reaction temperature will favor the direction that produces heat. In other words, the addition of heat to an exothermic reaction will shift the equilibrium towards the reactants, while the same change will shift an endothermic reaction towards product formation.

Answer 6

can i ask you guys a couple more Questions?

Answer 7

Sure!

Answer 8

One way to determine the degree of saturation of a solid-liquid solution is to drop a crystal of the solute into the solution. if the crystal sits at the botton of the container, the solution is ?
A. Saturated
b. unstaurated
c. Supersaturated
d. Concentrated

Answer 9

To calculate the molarity of a solution, you need to know the moles of the solute and the ?
A.Volume of the solvent
b. volume of the solution
c. Mass of the solution
d Volume of the solute

Answer 10

Wow, it's been a while since I've done this kind of thing. I think it's saturated. As for molarity...All I remember is that the concentration of a solution is expressed as the number of moles of solute per liter of solution but liter of solution isn't an option.

Answer 11

Well i just started this so
im a little confused

Answer 12

Im in connections academy

Answer 13

Maybe volume of the solution since liter is a unit of volume?

Answer 14

Cool! I'm in k12. I did Honors Chemistry last year but I tend to forget it all once I'm done with it.

Answer 15

What do you mean?

Answer 16

Sorry I couldn't help you more with your other questions.

Answer 17

Same lol i have short term memory

Answer 18

Its alright you earn a medal

Answer 19

Can you try to answer the volume one a little less confusing?

Answer 20

I think it might be volume of solution...but I'm not sure. Here is the link to another question on openstudy that might help. http://openstudy.com/study#/updates/52b28b36e4b02932bbbe1699

Answer 21

It has some of the same questions you are asking.

Answer 22

Oh and thanks for the medal! Let me know how you do.

Answer 23

Ok thanks!
