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: lnK2K1=ΔHR(1T21T1), where ΔH is the standard enthalpy change, R is the gas constant, and T1 and T2 are the initial and final temperatures, respectively.
insert step 4> Verify if the correct values for ΔH and K1 (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.
