The values of Δ H ∘ , temperature and pressure for the stated reactions are given. The value of Δ S surr is to be calculated in each case. Concept introduction: Entropy is the measure of degree of disorder or randomness. Entropy of surrounding ( Δ S surr ) decreases for endothermic process whereas, it increases for exothermic process.
