# Chemical equilibrium

1. Homework Statement
$$N_{2(g)}$$, 0.32M and $$H_{2(g)}$$, 0.66M are placed in a reaction vessel. The system reaches equilibrium when $$[H_{2(g)}]$$ = 0.30M. Calculate $$K_C$$

a) 10.7$$M^2$$
b) 4.00$$M^2$$
c) 2.67$$M^2$$
d) 1.67$$M^2$$

2. Homework Equations
Equilibrium constant formula

3. The Attempt at a Solution
This is just messing me up because the chemical equation isn't given. If I don't know the products, how do I get the equilibrium constant?
