Answer:

A. 0.16M H₂SO₄

Explanation:

In a reaction as:

Zn + H₂SO₄ → ZnSO₄ + H₂

The higher concentration of reactants, the faster rate of reaction.

That is explained because a higher concentration of reactants increase the probability of collision of molecules increasing rate (Collision theory).

Thus, the right answer is:

A. 0.16M H₂SO₄

I hope it helps!
