Consider the reaction A+B = C, with a standard free-energy change of -33.7 kJ/mol. If A, B, and C are mixed at initial concentrations 230 mm, 430 mM and 99 mm, respectively, at 25°C, the reaction (as written) will: O the reaction is at equilibrium o absorb ~ 17.0 kJ/mol of energy upon reaching equilibrium O proceed in the reverse direction, to produce more A and B O release ~ 17.0 kJ/mol of energy upon reaching equilibrium O proceed forward,...
