For the reaction 2 A(g) + B(g) → products, the following elementary steps are proposed.
Step 1: A(g) + A(g) ⇌ C(g) (fast)
Step 2: C(g) + B(g) → products (slow)
By what factor will the initial rate change if the initial concentration of A is doubled while the initial concentration of B remains the same?
a) It will increase eight-fold.
b) It will quadruple.
c) It will remain the same.
d) It will double.
