Consider the following reaction: 2CH₂OH(g) → 2 CH₂(g) + O₂(g) AH = +252.8 kJ (a) Is this reaction exothermic or endothermic? (b) Calculate the amount of heat transferred when 24.0 g of CH₂OH(g) is decomposed by this reaction at constant pressure. (c) For a given sample of CH,OH, 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 CH.(g) reacts completely with O₂(g) to form CH₂OH(g) at constant pressure?
