When 1mol of a gas burns at constant pressure, it produces 2430 j of heat and does 5 kj of work?

Convert 2430j to Kj that is divide by 1000

2430/1000=2.430

delta E = Q+W

q is the heat done

w is the work done and since is work is done is by the system therefore it is negative

w is therefore - 5kj

q=-2.430

delta E = - 2.430 + - 5 = - 7.43kj/mol
