Chemistry Question on Law Of Chemical Equilibrium And Equilibrium Constant
Some of the reactions and their equilibrium constants Kc are given. Choose the reaction which proceeds rarely at the given temperature.
A
2H2(g) + O2(g) ⇌ 2H20(g); Kc = 2.4×1047 at 500K
B
H2(g) + I2(g) ⇌ 2HI(g); Kc = 57.0 at 700K
C
H2(g) + Cl2(g) ⇌ 2HCI(g); Kc = 4.0×1031at 300K
D
N2(g) + O2(g) ⇌ 2N0(g); Kc = 4.8×1031 at 298K
E
H2(g) + Br2(g) ⇌ 2HBr(g); Kc = 5.4×1018 at 300K
Answer
N2(g) + O2(g) ⇌ 2N0(g); Kc = 4.8×1031 at 298K
Explanation
Solution
The correct option is (D) : N2(g) + O2(g) ⇌ 2N0(g); Kc = 4.8×1031 at 298K
