Molar heat capacity of water in equilibrium with ice at constant pressure is(in kJ/Kmol ?
1)0

2) infinity

3) 43.45

4) -43.45

The answer is infinity .

as ΔH is not equal to 0.

???ΔH=C_p ΔT.

as it is equilibrium ΔT=0.

       therefore, C_p=infinity..

Approve the answer

Heat capacity at constant pressure may be defined as the rate of change of enthalpy with temperature at constant pressure.Cp=dHdTSince water and ice is at equilibrium, there is no change in temperature. They are at same temperature. So dT =0 and we know that something divided by 0 is infinityThus Cp= infinity ( at constant pressure)

Answer infinity delta h = Cp delta t since t=0 answer is infinity because delta h /0 will become infinity

Dear Student,
Please find below the solution to your problem.

Δh = Cp delta t
since t=0
delta h /0 will become infinity

Thanks and Regards
