# I need to find K for the given conditions

I'm so confused about what to do for this problem... I know that I need to find K for the given conditions but I'm not quite sure how. Any help would be greatly appreciated

For each of the following sets of conditions, determine if the system is at equilibrium or not. For those not at equilibrium, state in which direction the system will shift.
It gives K as .0900 at 25 degrees Celsius for the reaction:
H2O(g) + Cl2O(g)<--> 2HOCl(g)
Then it gives several different conditions such as:
A) PH2O= 296 torr PCl2O= 15 torr PHOCl= 15 torr
B) 3.0 L flask contains .35 mol HOCl, .001 mol Cl2O and .98 mol H2O
C) 2.0 L flask contains .084 mol HOCl, .08 mol Cl2O and .98 mol H2O

A)

I believe the reaction will be towards the products because you have too many moles of gas on the left, so the reaction will work to react these gases and increase the product.

B)

There's very little ClO2 and so the equilibrium will be shifted to make more reactants.

C)

Equilibrium.

At any instant u have Kp = Kc

so calculate K for each given conditions And see whether it is equal to given K or not

U will have it in them ur book How to calculate the K in various conditions
