Question

When the temperature is decreased on the following system at equilibrium: I believe the answer is "In order to restore equilibrium, the reaction shift towards the reactants" because the decrease in temp reduces the reaction rate and therefore the equilibrium has to shift to the left. Is that the correct idea here?

2 HCl(aq) + Zn(s) <->  ZnCl2(aq) + H2(g) + heat

The reaction will not shift at all because equilibrium is independent of reaction rate

In order to restore equilibrium, the reaction shift towards the products

The reaction will not shift at all because equilibrium is independent of temperature

In order to restore equilibrium, the reaction shift towards the reactants

Explanation / Answer

when the temperature is decreased the rate of reaction for the exothermic rxn like above will move towards forward direction(products)
