Given the following two measurements of the equilibrium constant for a reaction,calculate $\Delta$H $\circ$ for the reaction.

Question

Quizplus · Accepted Answer

The correct answer is A because the change in free energy is given by the equation ΔG = -RTlnK, where R is the gas constant, T is the temperature in Kelvin, and K is the equilibrium constant. Substituting the given values into this equation, we get:ΔG = -8.314 J/mol·K * (298 K) * ln(9.3 × 10^4 / 2.6 × 10^3) = -256 kJ/mol
