Answer
(a) $$K_p = 0.15 $$
(b) $$K_p = 3.6 \times 10^{-7} $$
Work Step by Step
(a)
1. Calculate $\Delta n$ (n is the amount of moles of gases):
$$\Delta n = n_{products} - n_{reactants} = 2 - 1 = 1 $$
2 . Calculate Kp:
$$K_p = K_c(RT)^{\Delta n} = ( 6.1 \times 10^{-3} )(0.0821 \times 298 )^{ 1 }$$
$$K_p = 0.15 $$
(b)
1. Calculate $\Delta n$ (n is the amount of moles of gases):
$$\Delta n = n_{products} - n_{reactants} = 2 - 4 = -2 $$
2 . Calculate Kp:
$$K_p = K_c(RT)^{\Delta n} = ( 2.4 \times 10^{-3} )(0.0821 \times 1000.)^{ -2 }$$
$$K_p = 3.6 \times 10^{-7} $$
