hello maam/sir kindly help me with this one.. pleaseeee... kindly show solution also please... thanks in advance 7. Consider the following balanced thermochemical equationfor a reaction sometimes usedfor H2S production:%S8(s) + H2(g) → H2S(g)(a) Is this an exothermic or endothermic reaction?AHxn = -20.2 kJ(b) What is AHrxn for the reverse reaction?(c) What is AH when 3.2 mol of S8 reacts?(d) What is AH when 20.0 g of S8 reacts?

Given that - 1/8S8(s) + H2(g) -----> H2S(g) , ∆Hrxn = -20.2 kJ Here, 1/8 = 0.125 moles…
