  • 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: Option 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.
