### Calculating the ΔG of an ATP-Coupled Reaction**Question:**What is the ΔG of an ATP-coupled reaction where the endergonic component's ΔH = -30 kJ/mol, ΔS = -0.2 kJ/mol, and the reaction is taking place at 210K? Give your ΔG for the coupled reaction in kJ/mol. Hint: the ΔG of ATP hydrolysis is -30.5 kJ/mol.**Calculation Steps:**1. **Determine ΔG for the endergonic reaction component:** Using the Gibbs Free Energy equation: \[ ΔG = ΔH - TΔS \] Given: \[ ΔH = -30 \text{kJ/mol} \] \[ ΔS = -0.2 \text{kJ/mol·K} \] \[ T = 210 \text{K} \] Substitute the values into the equation: \[ ΔG = -30 \text{kJ/mol} - (210 \text{K} \times -0.2 \text{kJ/mol·K}) \] \[ ΔG = -30 \text{kJ/mol} + 42 \text{kJ/mol} \] \[ ΔG = 12 \text{kJ/mol} \]2. **Combine the ΔG values for the coupled reaction:** The overall ΔG for the coupled reaction is the sum of the ΔG values of the endergonic reaction and the ATP hydrolysis. Given: \[ ΔG_{\text{ATP hydrolysis}} = -30.5 \text{kJ/mol} \] \[ ΔG_{\text{coupled reaction}} = 12 \text{kJ/mol} + (-30.5 \text{kJ/mol}) \] \[ ΔG_{\text{coupled reaction}} = 12 \text{kJ/mol} - 30.5 \text{kJ/mol} \] \[ ΔG_{\text{coupled reaction}} = -18.5 \text{kJ/mol} \]**Answer:**\[\boxed{-18.5 \text{kJ/mol}}\]

The equation used to calculate the Gibbs free energy change of the reaction is: ......(1)…
