Multiple Choice Options

  • A 2NO(g)⇌N2(g)+O2(g)2NO(g)\rightleftharpoons N_2(g)+O_2(g)
  • B SO2(g)+NO2(g)⇌SO3(g)+NO(g)SO_2(g)+NO_2(g)\rightleftharpoons SO_3(g)+NO(g)
  • C H2(g)+I2(g)⇌2HI(g)H_2(g)+I_2(g)\rightleftharpoons 2HI(g)
  • D 2C(s)+O2(g)⇌2CO2(g)2C(s)+O_2(g)\rightleftharpoons 2CO_2(g)

Step-by-Step Verified Solution

As we know, K p = K c _ (RT) _ n g So, for reaction having same number of gaseous moles on reactants and products side will have same value of Kc and Kp otherwise their values are different. For reaction, 2NO (g) _ N 2(g) + O 2(g) _ n g = 2 � 2 = 0 _ K p = K c _ (RT) 0 _ K p = K c For reaction, SO 2(g) + NO 2(g) _ SO 3(g) + NO (g) _ n g = 2 � 2 = 0 _ K p = K c _ (RT) 0 _ K p = K c For reaction, H 2(g) + I 2(g) _ 2HI (g) _ n g = 2 � 2 = 0 _ K p = K c _ (RT) 0 _ K p = K c For reaction, H 2(g) + I 2(g) _ 2HI (g) _ n g = 2 � 2 = 0 _ K p = K c _ (RT) 0 _ K p = K c For reaction, 2C (s) + O 2(g) _ 2CO 2(g) _ n g = 2 � 3 = -1 _ K p = K c _ (RT) -1 _ K p � K c
