Evaluate K C for CO ( g ) + H 2 O ( g ) ⇌ C O 2 ( g ) + H 2 ( g ) . 2 moles each of CO and H 2 O are taken initially in a 1 L vessel and the equilibrium moles of C O 2 are 1.2.

Question

Evaluate K C ​ for CO ( g ) + H 2 ​ O ( g ) ⇌ C O 2 ​ ( g ) + H 2 ​ ( g ) . 2 moles each of CO and H 2 ​ O are taken initially in a 1 L vessel and the equilibrium moles of C O 2 ​ are 1.2.

TestHub · Accepted Answer

C O 2 ​ = H 2 ​ = 1.2 mol , so CO = H 2 ​ O = 2 − 1.2 = 0.8 mol . K C ​ = ( 1.2 × 1.2 ) / ( 0.8 × 0.8 ) = 1.44/0.64 = 2.25 (volume cancels since Δ n = 0 ). Answer: (A).
