Question

The reaction ${2SO2 +O2 <=> 2SO3 +}$ Heat, will be favoured by

• A. high temperature and low pressure
• B. low temperature and high pressure
• C. high temperature and high pressure
• D. low temperature and low pressure

Answer 1

Answer: (B)

low temperature and high pressure

Answer 2

Since reaction is exothermic it is favoured at low temperature. There is a decrease in number of moles hence reaction is favoured at high pressure.
