Answer:
a) is dependent on the concentration of A and B.
Explanation:
For a reaction:
A + B → C
That is first order with respect a and B have a rate of reaction (v) of:
v = k [A]¹ [B]¹ (1)
Where k is rate constant.
First order with respect a reactant means the exponent in the concentration of the reactant is 1.
Knowing this:
a) is dependent on the concentration of A and B. TRUE. The rate of reaction depends of A and B.
b) is dependent on the concentration of A . FALSE. The reaction depends also of B.
c) has smaller rate constants than first-order reactions regardless of reactant concentration . FALSE. Rate constant depends of several factors as temperature, type of reaction, etc.
d) is independent of reactant concentration . FALSE. It depends of A and B.
e) is always faster than first-order reactions due to loss of concentration dependence. FALSE. When the concentration of reactants is decreasing, the rate of reaction will also decrease.
I hope it helps!
