The following reaction: SO2 (g) <====> SO3 (g) + NO (g) having reached a state of equilibrium, was found to contain 0.40 M SO3, 0.30 M NO, 0.15 M NO2, and 0.20 M SO2. Calculate the equilibrium constant for this reaction. Describe the direction ad extent of a reaction.

Answer 1

SO2 (g) <====> SO3 (g) + NO (g)
We have a problem here. You must have omitted something on the left.

Answer 2

@DrBob222 I don't believe so Sir, that's how the question was given to me.

Answer 3

SO2 (g) <====> SO3 (g) + NO (g)
C'mon now. You're a better chemist than I if you can get NO on the right side and there is no hint of N on the left side. You can't get something from nothing.

Answer 4

It's rather obvious to me that the equation should be
SO2 (g) + NO2 <====> SO3 (g) + NO (g)
Write the equilibrium expression for the equation. plug in the values given in the problem and solve for K. If K > 1 the extent of the equilibrium is to the right; if K < 0 the equilibrium is to the left.

Answer 5

@DrBob222 Sorry Sir, you're right that makes more sense. Thank you for your help
