For a system in equilibrium, the rate constant for the forward reaction is represented by kf and the rate constant for the reverse reaction is represented by kr. Which equation represents the equilibrium constant for this reaction in the forward direction?

Hydrogenation reactions, in which h2 and an "unsaturated" organic compound combine, are used in the food, fuel, and polymer industries. in the simplest case, ethene (c2h4) and h2 form ethane (c2h6). if 140 kj is given off per mole of c2h4 reacting, how much heat (in mj) is released when 12 kg of c2h6 forms?
