Problem 44E

Enthalpy (Sections)

Consider the following reaction:

2 CH3OH(g)→ 2 CH4(g) + O2(g) ΔH = +252.8 kJ

(a) Is this reaction exothermic or endothermic? (b) Calculate the amount of heat transferred when 24.0 g of CH3OH(g) is decomposed by this reaction at constant pressure. (c) For a given sample of CH3OH, the enthalpy change during the reaction is 82.1 kJ. How many grams of methane gas are produced? (d) How many kilojoules of heat are released when 38.5 g of CH4(g) reacts completely with O2(g) to form CH3OH(g) at constant pressure?
