arlik [135]

Answer:

$\Delta _rH=-802.2kJ/mol$

Explanation:

Hello!

In this case, according to the given chemical reaction, it is possible to calculate the enthalpy change of the reaction via:

$\Delta _rH=\Delta _fH_{CO_2}+2\Delta _fH_{H_2O}-\Delta _fH_{CH_4}$

Since the enthalpy of formation of oxygen is 0. Thus, given the enthalpies of formation of gaseous carbon dioxide and water, we obtain:

$\Delta _rH=(-393.5kJ/mol)+2(-241.8kJ/mol)-(-74.9kJ/mol)\\\\\Delta _rH=-802.2kJ/mol$

Best regards!
