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 $A plus 2 text end text B rightwards arrow 3 C$ at 300 K and 310 K is $capital delta H subscript 300 end subscript$ and $capital delta H subscript 310 end subscript$ respectively then :

$Δ H_{300} > Δ H_{310}$
$Δ H_{300} < Δ H_{310}$
$Δ H_{300} = Δ H_{310}$
If $T_{2} > T_{1}$ then $Δ H_{310} > Δ H_{300}$ and if $T_{2} < T_{1}$ then $Δ H_{310} < Δ H_{300}$

The correct answer is: $capital delta H subscript 300 end subscript equals capital delta H subscript 310 end subscript$
