Question

1. What is the correct equilibrium constant expression for N2(g)+ 3H2(g)<--> 2NH3(g)? \text { a. } \frac{\left[\mathrm{NH}_{3}\right]}{\left[\mathrm{N}_{2}\right]\left[\mathrm{H}_{2}\right]^{3}} \text { b. } \quad \frac{\left[\mathrm{N}_{2}\right]\left[\mathrm{H}_{2}\right]^{3}}{\left[\mathrm{NH}_{3}\right]^{2}} \text { C } \frac{\left[\mathrm{N}_{2}\right]\left[\mathrm{H}_{2}\right]}{\left[\mathrm{NH}_{3}\right]} \text {

d. } \frac{\left[\mathrm{NH}_{3}\right]}{\left[\mathrm{N}_{2}\right]\left[\mathrm{H}_{2}\right]} \begin{aligned} &\text { e. }\\ &\left[\mathrm{N}_{2}\right]\left[\mathrm{H}_{2}\right]^{3} \end{aligned}
