Answer 4

you're right, R is a constant.

\(K_c\) is another constant, at that temperature.

T is in Kelvin.

\(Kelvin=273^oC+T(in~^oC) =273^oC+300^oC=573K\)

The trickiest part comes from \(\Delta n\) in the exponent.

\(n\) refers to the coefficients in the balanced equation
(for gases only, if you get a solid, it doesnt go into this).

\(\Large \underbrace{N_2}_{1}+\underbrace{3H_2}_{3}\rightleftharpoons \underbrace{2NH_3}_{2}\)

\(\large \Delta n=n_{products}-n_{reactants}=2-(3+1)=-2\)


hence the exponent is -2.
