For Which Of The Following Reactions Is The Ratio Kp/Kc Largest At 300 K?

A. Ni(CO)4(g) _ Ni(s) + 4CO(g) B. C(s) +2H2(g) _ CH4(g) C. CaCO3(s) _ CaO(s) + CO2(g) D. N2(g) + O2(g) _ 2 NO(g)

A. Ni(CO)4(g) _ Ni(s) + 4CO(g) The Kp/Kc ratio is equal to (RT)_n. K is a constant and the temperature is held constant. So, the Kp/Kc ratio depends on _n or the difference of moles of gaseous product and reactant. The reaction with the greatest Kp/Kc ratio is Ni(CO)4(g) _ Ni(s) + 4CO(g) with a _n of 3.
