For a reaction with two reactants A and B, if m = 1 and n = 0, the rate depends on which component?

Explanation:
The rate law expresses how the rate depends on the concentrations of the reactants: rate = k [A]^m [B]^n. Here m is 1 and n is 0, so the rate becomes rate = k [A]^1 [B]^0 = k [A]. A zero order in B means the rate is independent of B’s concentration; only A influences how fast the reaction occurs. Doubling [A] will double the rate, while changing [B] won’t affect it at all. So the rate is proportional to [A] only. The other forms would require different orders: including both A and B, or making A second order, or depending on B.
