Answer 1

To calculate AGxn, use the free energy equation AGxn = AHxn - T*ASxn. Plugging in the given values and solving, we find that AGxn = -623.8 kJ/mol.

Step-by-step explanation:

To calculate the AGxn for the given reaction, we need to use the free energy values provided. We can use the equation AGxn = AHxn - T*ASxn, where AHxn is the enthalpy change and ASxn is the entropy change.

By plugging in the values given and calculating AHxn and ASxn, we can then calculate AGxn.

AGxn = -622.2 kJ/mol - (298 K * 0.0052 kJ/(mol*K)) = -623.8 kJ/mol
