Is the value of the equilibrium constant at 525 K for each reaction in Problem 73 estimated correctly?

Verified step by step guidance
1
<insert step 1> Identify the reactions from Problem 73 that need to be evaluated for their equilibrium constants at 525 K.>
<insert step 2> Review the method used to estimate the equilibrium constant for each reaction. This could involve calculations using the Van't Hoff equation or other thermodynamic data.>
<insert step 3> Check if the temperature dependence of the equilibrium constant was considered correctly. This often involves using the Van't Hoff equation: \( \ln \frac{K_2}{K_1} = -\frac{\Delta H^\circ}{R} \left( \frac{1}{T_2} - \frac{1}{T_1} \right) \), where \( \Delta H^\circ \) is the standard enthalpy change, \( R \) is the gas constant, and \( T_1 \) and \( T_2 \) are the initial and final temperatures, respectively.>
<insert step 4> Verify if the correct values for \( \Delta H^\circ \) and \( K_1 \) (the equilibrium constant at the initial temperature) were used in the calculations.>
<insert step 5> Compare the estimated equilibrium constants with any available experimental data or literature values to assess the accuracy of the estimates.>
