If the molar ratio of A2(g)to A(.g.) is 5: 3 in a set of product gases , then the energy involved in the decomposition of 1 mole of A2B(.g.) is: Δ rH=(5/8)× 40+(3/8)× 50=43.75 k J / m o l

Q. Substance $A_{2} B (g)$ can undergo decomposition to form two set of products

If the molar ratio of $A_{2} (g) t o A (g)$ is 5 : 3 in a set of product gases , then the energy involved in the decomposition of 1 mole of $A_{2} B (g)$ is:

48.75 kJ/mol

43.75 kJ/mol

46.25 kJ/mol

64.2 kJ/mol

If the molar ratio of $A_{2} (g) t o A (g)$ is 5 : 3 in a set of product gases , then the energy involved in the decomposition of 1 mole of $A_{2} B (g)$ is:

$Δ_{r} H = \frac{5}{8} \times 40 + \frac{3}{8} \times 50 = 43.75 k J / m o l$
