Consider the reactions equilibrium ,
` 2SO_2 (g) + O_2(g) hArr 2SO_3 (g) , Delta H^(@) = - 198 `kJ
On the basis of Le- Chatelier's Principal , the condition favourable for the forward reaction is

A

lowering of temperature as well as pressure

B

increasing temperature as well as pressure

C

lowering the temperature and increasing the pressure

D

any value of temperature and pressure.

Text Solution

Verified by Experts

The correct Answer is:
C
The reaction is axothermic and involves a decrease in the number of moles. Therefore a decrease in temperature and an increase in pressure will favour the reaction.
