Statement 1: For 2SO2(g) + O2(g) ⇌ 2SO3(g) at 500 K, KP (in atm) is numerically less than KC (in mol/L).
Statement 2: KP = KC(RT)Δ ng, and here Δ ng = -1, so KP = KC/RT.
Options:
Answer:
A
Solution:
Δ ng = 2 - 3 = -1 KP = KC(RT)-1 = KC/RT, so Statement 2 is correct
With R = 0.082 L atm/mol/K and T = 500 K, RT = 41
KP = KC/41, which is numerically smaller than KC, so Statement 1 is correct
Statement 2 gives the reason for Statement 1, option (a).
