Consider this reaction: zn(s) + 2hcl(aq) zncl2(aq) + h2(g). which change could decrease the rate of production of zncl2?

Explanation:

In reaction:

We  know according to Le Chatelier's principle or "The Equilibrium Law" states that when a system experiences a disturbance (such as concentration, temperature, or pressure changes), it will respond to restore a new equilibrium state.

In this case rate of production of decreases when:

1. When concentration of HCl decreases.

2. When concentration of either or increases.

3. Increase in temperature because it is exothermic reaction.
