Question

Describes the rat of reaction between reagents A and B A+B=C Rate =k x [A] x [B] what happens to the rate if the concentration of A is doubled? if the concentration of B is doubled? if the concentration of both A and B are doubled?

Homework Answers

Answer #1

A+B=C

Rate =k x [A] x [B]

Rate depends on the concentration of both A and B. There is no exponent raise to A and B which both A and B combine together in an equal stoichiometric ratio of 1.

# If the concentration of A is doubled

new rate is Rate =k x [2A] x [B] = 2 times initial rate.

Similarly,

# If the concentration of B is doubled

new rate is Rate =k x [A] x [2B] = 2 times initial rate.

# If the concentration of both A and B are doubled

new rate is Rate =k x [2A] x [2B] = 4 times initial rate.
