Answer
(a) 0.77
(b) $3.8 \times 10^{-58} $
Work Step by Step
(a)
1. Calculate $\Delta n$ (n is the amount of moles of gases):
$$\Delta n = n_{products} - n_{reactants} = 2 - 2 = 0 $$
2 . Calculate Kp:
$$K_p = K_c(RT)^{\Delta n} = ( 0.77 )(0.0821 \times 1020. )^{ 0 }$$
$$K_p = 0.77 $$
(b)
1. Calculate $\Delta n$ (n is the amount of moles of gases):
$$\Delta n = n_{products} - n_{reactants} = 2 - 3 = -1 $$
2 . Calculate Kp:
$$K_p = K_c(RT)^{\Delta n} = ( 1.8 \times 10^{-56} )(0.0821 \times 570. )^{ -1 }$$
$$K_p = 3.8 \times 10^{-58} $$
