Equilibrium Constants and Reference States

The video tutorial explains how to calculate equilibrium constants for two reactions, focusing on the differences in reference states for water as a liquid and gas. It covers the use of delta G of formation and fugacity in these calculations, highlighting the impact of saturation pressure and reference conditions on the equilibrium constants.

What is the main difference between the two reactions discussed in the video?

• The type of reactants used

• The state of water involved

• The temperature at which reactions occur

• The presence of a catalyst

What is the equilibrium constant for the first reaction?

• 10

• 6.4

• 1.34

• 4.76

In the first reaction, what is the reference state condition for water?

• Vapor at one bar

• Solid at one bar

• Gas at one bar

• Liquid at one bar

What is the saturation pressure of water at 150 degrees Celsius used in the calculation?

• 4.76 bar

• 6.4 bar

• 1.34 bar

• 10 bar

How is the fugacity of water at equilibrium determined in the first reaction?

• By using the ideal gas law

• By measuring the saturation pressure

• By using the standard pressure

• By calculating the change in pressure

What is the equilibrium constant for the second reaction?

• 4.76

• 1.34

• 6.4

• 10

In the second reaction, what is the reference state condition for water?

• Solid at one bar

• Liquid at one bar

• Vapor at one bar

• Gas at one bar

Why is the equilibrium constant different for the two reactions?

• Different temperatures
