Question

For N2(g) + 3 H2(g) ↔ 2 NH3(g), Kp = 4.34 × 10-3 at 300℃. What is Kp or the reverse reaction?

Answer 1

$K_P=$ $P_{NH_3}\over P_{N_2}P_{H_2}$

$K_P$ for reverse react ion reaction$=$ $1\over K_p$

$=$ $1\over 4.34\times 10^{-3}(100°C)$

$=230.414$

$\therefore$ $K_p$ for reverse reaction$=230.414$
