Chemical Equilibrium Calculation at 430°C

What is the equilibrium concentrations of H2, I2, and HI at 430°C?

Can you calculate the equilibrium concentrations of each gas at 430°C in M?

Equilibrium Concentrations of Gases

The equilibrium concentrations of H2, I2, and HI at 430°C can be calculated using the given initial concentrations and the equilibrium constant Kc.

Chemical equilibrium is always exciting to explore, especially when we need to calculate the equilibrium concentrations of gases at a specific temperature like 430°C. In this case, we have a mixture of H2, I2, and HI enclosed in a vessel and heated to 430°C.

By utilizing the equation Kc = [HI]^2 / ([H2] * [I2]) and the given initial concentrations of 0.507 M H2, 0.420 M I2, and 0.949 M HI, we can determine the equilibrium concentrations of each gas at 430°C.

To calculate the equilibrium concentrations, we need to set up an expression for each gas based on the change in concentration at equilibrium compared to the initial concentration. By solving these expressions with the equilibrium constant Kc = 54.3, we can find the equilibrium concentrations of H2, I2, and HI for the given reaction.

Chemical equilibrium is a fascinating concept where the forward and reverse reactions reach a balance, and the concentrations of reactants and products remain constant over time. Understanding how to calculate equilibrium concentrations can enhance our knowledge of chemical reactions and their behavior under different conditions.
