Substance $A_2B(g)$ can undergoes decomposition to form two set of products If the molar ratio of $A_2(g)$ to $A(g)$ is $5 : 3$ in a set of product gases, then the energy involved in the decomposition of $1\, mole$ of $A_2B(g)$ is
→${A_2}B(g) \to {A_2}(g) + B(g);\,\,\,\Delta {H^o} = 40\,kJ/mol$
${A_2}B(g) \to A(g) + AB(g);\,\,\,\Delta {H^o} = 50\,kJ/mol$
