Question

The conditions favourable for the reaction; 2SO2(g) + O2(g) leftharpoons 2SO3(g); Δ H° = - 198 kJ are: (A) Low temperature, high pressure (B) Any value of T and P (C) Low temperature and low pressure (D) High temperature and high pressure

Tardigrade Admin · Accepted Answer

High pressure favours the reaction showing decrease in mole or volume, i.e., forward reaction. A lso low temperature favours exothermic reaction, i.e., forward reaction.

Q. The conditions favourable for the reaction; 2SO2(g)​+O2(g)​⇌2SO3(g)​;ΔH∘=−198kJ are:

Low temperature, high pressure

Any value of T and P

Low temperature and low pressure

High temperature and high pressure

High pressure favours the reaction showing decrease in mole or volume, i.e., forward reaction. A lso low temperature favours exothermic reaction, i.e., forward reaction.
