The molar heat capacities at constant pressure (assumed constant with respect to temperature) for A, B and C are in ratio of 3 : 1.5 : 2.0. The enthalpy change for the exothermic A + 2B → 3C at 300 K and 310 K is ∆H300 and ∆H310 (magnitudes) respectively then :
- ∆H300 > ∆H310
- ∆H300 < ∆H310
- ∆H300 = ∆H310
- if T2 > T1 then ∆H310 > ∆H300 and if T2 < T1
then ∆H310 < ∆H300
Answer
(C) ∆ H 300 = ∆ H 310
