17.04 The Standard State Gibbs Energy of Reaction

Standard State Gibbs Energy of Reaction (4:19) (msu.edu)

The standard state Gibbs energy of reaction depends only on temperature. Thus the equilibrium constant is also dependent only on temperature. The fugacities of the components in the reacting mixture change until the argument in the logarithm term reaches the value given by the equilibrium constant.

Comprehension Questions:

1. Calculate the heat of reaction for CO + 2H2 = CH3OH at 298K.
2. Calculate the Gibbs energy of reaction for CO + 2H2 = CH3OH at 298K.
3. For the reaction of CO + 2H2 = CH3OH, does Ka (equilibrium constant) increase, decrease, or stay the same as we increase the pressure?
