This is not the right set up for the equation.

Explanation:

In order to find the grams you would want the moles to "cancel" each other out. The correct way to set up this equation is seen in the photo.

c, liquids evaporate, creating a gas

consider the reaction below.

 no rx

at 500 k, the reaction is at equilibrium with the following concentrations.

[pci5]= 0.0095 m

[pci3] = 0.020

[ci2] = 0.020 m

what is the equilibrium constant for the given reaction?

0.042
