Analysis of the gases in a sealed reaction vessel containing $\mathrm{NH}_{3}, \mathrm{N}_{2},$ and $\mathrm{H}_{2}$ at equilibrium at $400^{\circ} \mathrm{C}$ established the concentration of $\mathrm{N}_{2}$ to be 1.2 $\mathrm{M}$ and the concentration of $\mathrm{H}_{2}$ to be 0.24 $\mathrm{M}$$\mathrm{N}_{2}(g)+3 \mathrm{H}_{2}(g) \rightleftharpoons 2 \mathrm{NH}_{3}(g) \qquad K_{c}=0.50$ at $400^{\circ} \mathrm{C}$Calculate the equilibrium molar concentration of $\mathrm{NH}_{3}$

So for this problem, we're taking a look at the equilibrium of nitrogen gas plus hydrogen gas and the production of ammonia gas, and were given the value for the equilibrium constant as well as the concentrations of nitrogen and hydrogen. And we want to find what the concentration of ammonia is going to be in this reaction vessel. If it's at equilibrium, the first thing that we should do is write out what our equilibrium expressions but you look like. So we have products over reactions. It means we're going to have ammonia on the top squared, the concentration of ammonia squared, and the reason for that is because ammonia has a coefficient to, and that's going to be over. A denominator of the concentration of nitrogen multiplied by the concentration of hydrogen concentration of hydrogen is to the third because it's coefficient is three. So now we just rearrange this equation to be written in terms of the variable we're trying to solve in this case a moment. The concentration of ammonia, which is going to be equal to the square root of the product. Casey times the concentration of nitrogen multiplied by the cube concentration of Hardin It's really all we need to do from here, Miss. Fill in our values. So we're going to have The concentration of nitrogen is equal to the square root of Casey, which is 0.5 multiplied by the concentration of nitrogen at 1.2 multiplied by the cube concentration of hydrogen gas, which is 0.24 We're gonna take the square root of that whole term. And if we do that, what we find is that the concentration of ammonia within this reaction facility equilibrium is going to be zero 0.91 Mueller.
