1 mole `N_2` and 3 moles of `H_2` are taken in a 4 litre flask. If `0.25%` of `N_2` is converted to `NH_3` at equilibrium and the reaction is `N_2(g)+3H_2(g)iff2NH_3(g)`. Then calculate the value of `K_c` under that condition.
Prove that for the reaction `aA_2(g)+bB_2(g)iffcAB(g)` the value of the ratio `K_p/K_c` is 1 when a+b=c.
