Question : If the equilibrium constants for the systems H2 + I2 < = > 2HI and 2HI < = > H2 + I2 are K1 and K2 respectively, the relationship between K1 and K2 is :
Option 1: K1 = K2
Option 2: K1 = 2K2
Option 3: K1 = K2 /2
Option 4: K1 = 1/K2
Correct Answer: K1 = 1/K2
Solution : The correct option is K1 = 1/K2.
