Jen is running an experiment about the dissociation of HI gas. She writes her equation to be: 2HI (g) = H2 (g) + I2 (g) Then she looks up the literature and databases. She finds that the equillibrium constant of HI formation from hygrogen and iodine gasses is 0.4 under the standard condition. She does not want to change her reaction direction because many other calculations such as enthalpy, entropy, and free energy are based on the reaction direction she has picked. What the equillibrium constant she should use under the standard condition? Keq = ______

Question

Jen is running an experiment about the dissociation of HI gas. She writes her equation to be:

2HI (g) = H2 (g) + I2 (g)

Then she looks up the literature and databases. She finds that the equillibrium constant of HI formation from hygrogen and iodine gasses is 0.4 under the standard condition.

She does not want to change her reaction direction because many other calculations such as enthalpy, entropy, and free energy are based on the reaction direction she has picked. What the equillibrium constant she should use under the standard condition? Keq = ______
