The equilibrium of an endothermic reaction which proceeds with an increase in volume can be shifted in the reverse direction by____________
A. increasing the temperature and decreasing the pressure B. decreasing the temperature and increasing the pressure C. decreasing the temperature and decreasing the pressure D. increasing the temperature and increasing the pressure
Correct Answer: B
Explanation
- For an exothermic reaction, a decrease in temperature favours the forward reaction while an increase in temperature favours the reverse reaction. - For an endothermic reaction, an increase in temperature favours the forward reaction while a decrease in temperature favours the reverse reaction. - For a reaction that proceeds with an increase in gaseous moles, a decrease in pressure favours the forward reaction while an increase in pressure favours the reverse reaction. - For a reaction that proceeds with a decrease in gaseous moles, an increase in pressure favours the forward reaction while a decrease in pressure favours the reverse reaction.
