I have a quick question.

How does this work:
ln Keq = 29.05
Keq = 1.12 * 10^23

What was plugged in the calculator to get Keq?

Keq = (products)/(reactants)

In the numerator, it's
product*product
In the denominator it's
reactant(reactant.
For both products and reactants, each is raised to the power indicated by the coefficient in the balanced equation.
