Consider the reaction equilibrium, `2SO_(2(g)) + O_(2(g))hArr , Delta H^(@) = - 198 kJ` . On the basis of Le-Chatelier's principle, the condition favourable for the forward reaction is

A

lowering of temperature as well as pressure

B

increasing of temperature as well as pressure

C

lowering of temperature and increasing of pressure

D

any value of temperature and pressure

Text Solution

Verified by Experts

The correct Answer is:
C
As the reaction in the forward direction is exothermic `(DeltaH` is negative ) and proceeds with a decrease in number of moles of gaseous components, high pressure and low temperature will favour the forward reaction.
