standard enthalpy of combustion at 25 ° C of C (graphite), and CO gas are respectively -393 kJ/mol and -283kJ/mol.

a) Calculate the standard enthalpy at 25 ° C, formation of CO gas.
b) When reacting to constant pressure with 140 g of CO excess O2 to form CO2 gas. How much heat will come off in this reaction?

Atomic mass: C=12 and O=16
