Which of the following is true for all exergonic reactions? a. the reaction goes only in a forward direction: all reactants will be converted to products, but no products will be converted to reactants. b. the reaction proceeds with a net release of free energy. c. a net input of energy from the surroundings is required for the reactions to proceed. d. the products have more total energy than the reactants. e. the reactions are rapid.

answer: 802.3 kilo joules of energy represents 191.75 kilo calorie of energy.

explanation:

energy released during combustion of one mole methane = 802.3 kilo joules

if 1 kilo joule = 0.239006   kilo calorie

then ,802.3 kilo joule will be = 802.30.239006 kilo calorie

802.3 kilo joule = 191.75 kilo calorie

hence, the energy in kilo calorie is 191.75 kilo calorie.
