**Transcription:**Calculate \( K_{eq} \) for a \( \Delta G^\circ \) value of 6.9 kcal/mol at 25 °C.**Explanation:**This text presents a problem that involves calculating the equilibrium constant (\( K_{eq} \)) for a chemical reaction using the standard free energy change (\( \Delta G^\circ \)) value, which is given as 6.9 kcal/mol at a temperature of 25 °C. The calculation typically involves the relationship between \( \Delta G^\circ \) and \( K_{eq} \) given by the equation:\[ \Delta G^\circ = -RT \ln K_{eq} \]Where:- \( \Delta G^\circ \) is the standard free energy change.- \( R \) is the universal gas constant (1.987 cal/mol·K or 8.314 J/mol·K, depending on the units used).- \( T \) is the temperature in Kelvin.- \( K_{eq} \) is the equilibrium constant.To solve this, convert 25 °C to Kelvin (298 K) and use the appropriate units for \( R \).
