At 25 ? C, ? G_r^o for the reaction 2SO₂(g)+ O₂(g) $f$ 2SO₃(g) Is - 141.74 kJ·mol ^- ¹.Calculate the value of K_c for this reaction.

Question

Quizplus · Accepted Answer

The value of Kc can be calculated using the Gibbs free energy change and the ideal gas constant. The Gibbs free energy change is given by the equation:ΔG = -RTlnKwhere:ΔG is the Gibbs free energy changeR is the ideal gas constant (8.314 J/mol·K)T is the temperature in KelvinK is the equilibrium constantSubstituting the given values into the equation, we get:-141.74 kJ/mol = -(8.314 J/mol·K)(298 K)lnKSolving for K, we get:K = 1.74 x 10^26
