At T(K), K_C value for the reaction 1 3 ~N ₂( ~g ) H ₂( ~g ) 2 3 NH ₃( ~g ) is 50 . The K _ C value for the reaction 2 NH ₃( ~g ) N ₂( ~g )+3 H ₂( ~g ) at the same temperature is
Options
- A4 10⁻⁶
- B8 10⁻⁶
- C6 10⁻⁶
- D8 10⁻³
Correct answer
B. 8 10⁻⁶
Step-by-step solution
1 3 ~N ₂+ H ₂ 2 3 NH ₃ ~K _ C =50 given. Multiply by 3 in eq ^ n N ₂+3 H ₂ 2 NH ₃ . Reverse eq (2) K _ C ^ =(50)^3 aligned & 2 NH ₃ N ₂+3 H ₂ ~K _ C ^ = ( 1 50 )^3 & K _ C ^ = 1 50 1 50 1 50 =8 10⁻⁶ . aligned
