First, make sure to balance your equation.
3H2(g) + N2(g) ⇄ 2NH3(g)
Now, you can write your Kc expression. Remember that Kc is products over reactants, and the exponent for each product or reactant is based on its coefficient.
Kc = [NH3]^2 / [H2]^3[N2]
A. volcanoes do not result
A + B → AB: ✔ synthesis
AB → A + B: ✔ decomposition
Hydrocarbon + O2 → CO2 + H2O: <span>✔ combustion</span>
AB + CD → AD + CB: <span>✔ replacement</span>
Answer:
1 m = 1/1000 km; 1 sec = 1/3600 hr
1 m/sec = 3600/1000 km/hr = 18/5 km/hr
