Question 1 2 pts 2 moles A and 10 moles B are introduced into a reactor at 1 atm and 48 C. The reaction happens base on the following equation : A+B=2C AH (1atm, 25 C)=-1,070 kJ At the end of the reaction the temperature of remaining species in the reactor are 61 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. Note: A will be fully consumed. B is in excess and some of it will remain at the end of the reaction. Report your answer up to 2 decimal points. Do not truncate any intermediate steps, but only the final result
