At 25 $\circ$ C,$\Delta$G r o for the reaction 2SO 2 (g)+ O 2 (g) ? 2SO 3 (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 formula:

KC = e^(-ΔG/RT)

where ΔG is the standard Gibbs free energy change, R is the gas constant, and T is the temperature in Kelvin.

Substituting the values given in the problem, we get:

KC = e^(-(-141.74 kJ/mol)/(8.314 J/mol·K * 298 K))

KC = 1.74 × 10^10 (approx.)

Therefore, the answer is A.
