The values of K P /K C for the following reactions at 300 K are, respectively : (At 300 K, RT = 24.62 dm 3 atm mol –1 )
N 2 (g) + O 2 (g) 
2NO(g)
N 2 O 4 (g) 
2NO 2 (g)
N 2 (g) + 3H 2 (g) 
2NH 3 (g)
Text Solution
Verified by ExpertsThe correct answer is:
B
Δ n g = 0 ; 
= 1
Δ n g = 2 – 1 = 1 ; 
= (RT) 1 = (24.62) 1 Δ n g = 2 – 4 = –2 ; 
= (RT)
–2 = (24.62) –2 = 1.65 × 10 –3
