Match the column.
Column –I | Column -II |
(i) CO2 (g) + H2O(λ)⎯→ H2CO3 (aq) | [A] Low temperature is favoured |
(ii) CO2 (g) + 2H2 (g) ⎯→ CH3OH (λ),ΔH = – 91 | [B] High temperature is favoured |
(iii) N2O4 (g) ⎯→ 2NO2 Δform H0 (N2O4 , g) = 9.2 kJ/mol Δform H0 (NO2, g) = 33.2 kJ/mol | [C] Low pressure is favoured |
(iv) N2 (g) + O2 (g) ⎯→ 2NO(g) ΔrH0 = 90 | [D] High pressure is favoured |
