The fuel in high-efficiency natural gas vehicles consists primarily of methane (CH4).
(a) How much heat is produced in burning 1 mol of CH4(g) under standard conditions if reactants and products are brought to 298 K and H2O(l) is formed?
(b)What is the maximum amount of useful work that can be accomplished under standard conditions by this system?
