Question
The molar heat capacities at constant pressure (assumed constant with respect to temperature) at A,B and C are in ratio of 3 : 1.5 : 2.0 The enthalpy change for the exothermic reaction A + 2B → 3C at 300 K and 310 K is ᐃH300 and ᐃH310 respectively then :
Options
A.ᐃH300 > ᐃH310
B.ᐃH300 < ᐃH310
C.ᐃH300 = ᐃH310
D.if T2 > T1 then ᐃH310 > ᐃH300 and if T2 < T1 then ᐃH310 < ᐃH300
