2 moles A and 8 moles B are introduced into a reactor at 1 atm and 32 C. The reaction happens base on the following

2 moles A and 8 moles B are introduced into a reactor at 1 atm and 32 C. The reaction happens base on the following equation :

A+B=2C H (1atm, 25 C)=-1,374 kJ

At the end of the reaction the temperature of remaining species in the reactor are 72 C.

Calculate the total change of enthalpy in this system in kJ.

Cp,a = 1 KJ/mol.K

Cp,b = 2 KJ/mol.K

Cp,c = 3 KJ/mol.K

Note: A will be fully consumed. B is in excess and some of it will remain at the end of the reaction.
