Question

If one mole of CO(g) is oxidised to CO2(g) in presence
of oxygen then the difference of heat change at
constant pressure and heat change at constant volume
will be
(1)-RT
(2)-RT/2
(3)-RT/3
(4)1/RT​

Answer 2

Explanation:

CO(g)+1/2 O2-------->CO2(g)

1mol 1/2mol 1mol

∆ng=1-1.5= -0•5

∆h=∆G+∆nRT

∆h-∆G= -0.5RT

∆h-∆G= -RT/2
