Question

A reaction $A(aq) + B(aq) \rightleftharpoons C(aq)$ has a standard free-energy change of $-4.85 \text{ kJ/mol}$ at $25 \degree C$. What are the concentrations of A, B, and C at equilibrium if, at the beginning of the reaction, their concentrations are 0.30 M, 0.40 M, and 0 M, respectively?

Step 1

The relationship between ΔG° and K is given by the equation: ΔG° = -RT ln(K), where R is the gas constant (8.314 J/mol∙K) and T is the temperature in Kelvin (25°C = 298 K). Rearranging the equation to solve for K: K = e^(-ΔG°/RT) Plugging in the values: K = Show more…
