Question
. What is the effect of the increase of temperature on the equilibrium of the reaction?
- Equilibrium is shifted to the left
- Equilibrium is shifted to the right
- Equilibrium is unaltered
- Reaction rate does not change
The correct answer is: Equilibrium is shifted to the left
It is an exothermic reaction, so high temperature favours backward reaction. Hence, equilibrium is shifted towards the left.
