The molar heat capacities at constant pressure (assumed constant with respect to temperature) of A, B and C are in ratio of `1.5 : 3.0 : 2.5`. If enthalpy change for the exothermic reaction `A+2B rarr 3C` at `300 K` and `310 K` is `DeltaH_(1)` and `DeltaH_(2)` respectively then
A. `DeltaH_(1) gt DeltaH_(2)`
B. `Delta_(1) lt DeltaH_(2)`
C. `DeltaH_(1)=DeltaH_(2)`
D. If `T_(2) gt T_(1)` then `DeltaH_(2) gt DeltaH_(1)` 7 if `T_(2) lt T_(1)` then `DeltaH_(2) lt DeltaH_(1)`
