Answer:
a) The rate of reaction increases by factor of 2.
b) The rate of reaction increases by factor of 0.25.
c) The rate of reaction increases by factor of 9.
Explanation:
a)
Rate of the reaction ;
if [A] is doubled, then rate of the reaction = R'
The rate of reaction increases by factor of 2.
b)
Rate of the reaction ;
if [B] is halved, then rate of the reaction = R'
The rate of reaction increases by factor of 0.25.
c)
Rate of the reaction ;
if [C] is tripled, then rate of the reaction = R'
The rate of reaction increases by factor of 9.
