Question

The heat of combustion of methane at 298° K is expressed by $CH_{4(g)} + 2O_{2(g)} \longrightarrow CO_{2(g)} + 2H_2O$ and $\Delta H$ = 890.2 kJ. Magnitude of $\Delta E$ of reaction at this temperature is
(a) infinity
(b) equal to $\Delta H$
(c) less than $\Delta H$
(d) greater than $\Delta H$

Answer 1

(c) part is the correct option
