At equilibrium, the concentration of NO in the vessel was 0.161 M . Calculate the value of \( \mathrm{K}_{\mathrm{c}} \) for the following reaction. Report the value of Kc to 2 significant figures. \[ 2 \mathrm{H}_{2}(g)+2 \mathrm{NO}(g) \rightleftharpoons 2 \mathrm{H}_{2} \mathrm{O}(g)+\mathrm{N}_{2}(g) \] You do not need to show your work for steps 1-3, but must show your work for steps 4-6 1. Calculate the initial concentrations of NO and \( \mathrm{H} 2 . \mathrm{M}=\mathrm{mot} / \mathrm{L} \). 2. Set up a RICE table. Fill in initial concentrations, fill in the equilibrium concentration of NO. 3. Calculate the change in concentration of NO and then calculate the equilibrium concentrations of \( \mathrm{H}_{2}, \mathrm{H}_{2} \mathrm{O} \) and \( \mathrm{N}_{2} \). 4. Write the equilibrium constant expression. 5. Plug in the equilibrium concentrations into the equilibrium constant expression. 6. Calculate \( K \).
