Question

The formation of a solid when two liquids are mixed indicates a reaction.
True
False
Increased concentration generally increases the reaction rate.
True
False
Increased temperature generally decreases the rate of a reaction.
True
False
You may normally expect a slow reaction rate if a large A.E. is required.
True
False
Raising the temperature of a reacting system increases the rate of the reaction, but does NOT increase the:
During the reaction P4 + 5O2 → P4O10, 1.5 moles of product were made in seconds. What is the rate of reaction?

Answer 1

Formation of a solid when two liquids are mixed indicates a precipitation reaction.

Answer 2

do you know any other ones

Answer 3

Increasing concentration generally increases reaction rate. http://www.chemguide.co.uk/physical/basicrates/concentration.html

Answer 4

Increasing temp generally increases reaction rate. http://www.chemguide.co.uk/physical/basicrates/temperature.html

Answer 5

The rate constant of a reaction increases exponentially when the activation energy decreases. Because the rate of a reaction is directly proportional to the rate constant of a reaction, the rate increases exponentially as well.
