MCQ
In the Contact process, the oxidation of SO2 to SO3 is exothermic. To get a good yield, the reaction:
Unit-9 Chemical Equilibrium
A is favoured by a very high temperature
B is favoured by a low temperature but is then slow
C is not affected by temperature
D must be done without a catalyst
Explanation

Since the forward reaction is exothermic, a low temperature favours SO3, but a moderate temperature is used as a compromise for a reasonable rate.
