A chemistry student needs to calculate the standard enthalpy change for the combustion reaction of methane gas (CH4) at 298 K and 1 atm pressure. The equation for the reaction is:CH4(g) + 2O2(g) --> CO2(g) + 2H2O(l)Given the following standard enthalpies of formation at 298 K:ΔHf(CO2) = -393.5 kJ/molΔHf(H2O) = -285.8 kJ/molΔHf(CH4) = -74.8 kJ/molCalculate ΔHrxn, the standard enthalpy change for the combustion reaction of methane gas.
