If 42.0 kJ of heat is added to a 32.0 g sample of liquid methane under 1 atm of pressure at a temperature of -170°C, what are the final state and temperature of the methane once the system equilibrates? Assume no heat is lost to surrounding. The normal boiling point of methane is -161.5°C. The specific heat of liquid and gaseous methane are 3.48 and 2.22 J/g-K, respectively. deltaHvap = 8.20 kJ/mol. Molar mass of CH4 = 16.04 g/mol.

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
