Question

Four identical zinc plates are placed in four different solutions of sulfuric acid (H2SO4). The following reaction occurs: Zn + H2SO4 ZnSO4 + H2 In which concentration of sulfuric acid solution would the reaction occur the fastest?

A. 0.16 M H2SO4
B. 0.01 M H2SO4
C. 0.016 M H2SO4
D. 0.1 M H2SO4

Answer 1

the answer is A. 0.16 M H2SO4

Answer 2

A. 0.16M H₂SO₄

Step-by-step 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
