The correct Answer is:
To calculate the standard enthalpy of solution of \( \text{AgCl(s)} \) in water, we can use the following reaction: \[ \text{AgCl(s)} \rightarrow \text{Ag}^+(aq) + \text{Cl}^-(aq) \] The standard enthalpy of solution (\( \Delta H_{sol} \)) can be calculated using the formula: \[ \Delta H_{sol} = \sum \Delta H_f^{\circ} \text{(products)} - \sum \Delta H_f^{\circ} \text{(reactants)} \] ### Step 1: Identify the enthalpy of formation values We have the following values from the question: - \( \Delta H_f^{\circ}(\text{AgCl(s)}) = -127.07 \, \text{kJ/mol} \) - \( \Delta H_f^{\circ}(\text{Ag}^+(aq)) = 105.58 \, \text{kJ/mol} \) - \( \Delta H_f^{\circ}(\text{Cl}^-(aq)) = -167.35 \, \text{kJ/mol} \) ### Step 2: Write the equation for \( \Delta H_{sol} \) Using the values, we can substitute them into the equation: \[ \Delta H_{sol} = \left( \Delta H_f^{\circ}(\text{Ag}^+) + \Delta H_f^{\circ}(\text{Cl}^-) \right) - \Delta H_f^{\circ}(\text{AgCl}) \] ### Step 3: Substitute the values into the equation Now, substituting the values we have: \[ \Delta H_{sol} = \left( 105.58 \, \text{kJ/mol} + (-167.35 \, \text{kJ/mol}) \right) - (-127.07 \, \text{kJ/mol}) \] ### Step 4: Calculate the sum of the products Calculating the sum of the products: \[ \Delta H_{sol} = \left( 105.58 - 167.35 \right) + 127.07 \] Calculating \( 105.58 - 167.35 \): \[ = -61.77 \, \text{kJ/mol} \] ### Step 5: Add the enthalpy of formation of \( \text{AgCl} \) Now, adding \( 127.07 \, \text{kJ/mol} \): \[ \Delta H_{sol} = -61.77 + 127.07 = 65.30 \, \text{kJ/mol} \] ### Final Answer Thus, the standard enthalpy of solution of \( \text{AgCl(s)} \) in water is: \[ \Delta H_{sol} = 65.30 \, \text{kJ/mol} \]

To calculate the standard enthalpy of solution of \( \text{AgCl(s)} \) in water, we can use the following reaction: \[ \text{AgCl(s)} \rightarrow \text{Ag}^+(aq) + \text{Cl}^-(aq) \] The standard enthalpy of solution (\( \Delta H_{sol} \)) can be calculated using the formula: ...
