The equilibrium constant of a system, K, can be related to the standard free energy change, AG using the following equation: AG = -RT In K where T is a specified temperature in kolvins (usually 298 K) and R is equal to 8.314 J/(K-mol). Under conditions other than standard state, the following equation applies AG=AG" + RT In Q In this equation, Q is the reaction quotient and is defined the same manner as K except that the concentrations or pressures used are not necessarily the equilibrium values. What is the free energy change, AG, in kilojoules for the reaction under these conditions? Express your answer numerically in kilojoules. ▸ View Available Hint(s) AG-20 (atm) C₂H₂(g) 4:45 H₂(g) 5.75 C₂He(g) 525 10:2 | ΑΣΦ kJ

The equilibrium constant of a system, K, can be related to the standard free energy change, AG using the following equation: AG = -RT In K where T is a specified temperature in kelvins (usually 298 K) and R is equal to 8.314 J/(K-mol). Under conditions other than standard state, the following equation applies AG AG" + RT In Q In this equation, Q is the reaction quotient and is defined the same manner as K except that the concentrations or pressures used are not necessarily the equilibrium values.
