Question- Calculate the enthalpy (?H?) of reaction (kJ) for the equation as written. If the answer is negative, enter the sign and then the magnitude. Express your answer to three significant figures.

CH3COOH(l) + 2O2(g) ? 2CO2(g) + 2H2O(l)

Formula Molar Mass (g/mol) ?G°f (kJ/mol) ?H°f (kJ/mol) S° (J/(K mol))

CH3COOH(l) 60.05 -484.5

O2(g) 31.999 0

CO2(g) 44.01 -393.5

H2O(l) 18.015 -285.83

T = 298 K R = 8.314 J/(K mol)
