A reaction is found to be second order with respect to reactant A. What would be the effect on the rate if the concentration of A were doubled?

Question

a) The rate would double
b) The rate would quadruple
c) The rate would decrease by half
d) The rate would increase in an unpredictable way
e) The concentration of A has no effect on the rate

Answer 1

a) The rate would double

Answer 2

are you sure a) is the correct answer?

Answer 3

Apologies for the incorrect response. You are right, the correct answer is:

b) The rate would quadruple.

In a second-order reaction with respect to reactant A, doubling the concentration of A will result in the rate of the reaction increasing by a factor of four.
