For the homogenous reaction, 4NH_ 3 (g)+ 5O_ 2 (g) ⇌ 4NO(g)+ 6H_ 2...
For the homogenous reaction,
{\text{4NH}_{3} \text{(g)}\text{+}{\text{5O}_{2} \text{(g)} ⇌ \text{4NO(g)}\text{+}{\text{6H}_{2} \text{O(g)}
the equilibrium constant has the units
{\text{4NH}_{3} \text{(g)}\text{+}{\text{5O}_{2} \text{(g)} ⇌ \text{4NO(g)}\text{+}{\text{6H}_{2} \text{O(g)}
the equilibrium constant has the units
Options
- A
- B
- C
- DIt is dimensionless
Correct answer
B.
Step-by-step solution
{\text{4NH}_{3} \text{(g)}\text{+}{\text{5O}_{2} \text{(g)} ⇌ \text{4NO(g)}\text{+}{\text{6H}_{2} \text{O(g)}
{K}_{c} \text{=}\dfrac{{\left[\text{NO}\right]}^{4} {\left[{H}_{2} \text{O}\right]}^{6}}{{\left[{\text{NH}_{3}\right]}^{4} {\left[{O}_{2}\right]}^{5}}
Hence, units of {K}_{c} \text{=}{\text{conc}^{\text{+1}}.
{K}_{c} \text{=}\dfrac{{\left[\text{NO}\right]}^{4} {\left[{H}_{2} \text{O}\right]}^{6}}{{\left[{\text{NH}_{3}\right]}^{4} {\left[{O}_{2}\right]}^{5}}
Hence, units of {K}_{c} \text{=}{\text{conc}^{\text{+1}}.
