If 100 mole of H2O2 decompose at 1 bar and 300 K, the work done (kJ) by one mole of O2(g) as it expands against 1 bar pressure is : 2H2O2(l) $\rightleftharpoons$ 2H2O(l) + O2(g) (R = 8.3 J K $-$1 mol$-$1)

Question

If 100 mole of H₂O₂ decompose at 1 bar and 300 K, the work done (kJ) by one mole of O₂(g) as it expands against 1 bar pressure is :

2H₂O₂(l) $\rightleftharpoons$ 2H₂O(l) + O₂(g)

(R = 8.3 J K ^$-$1 mol^$-$1)
