Key Idea For the reaction C ( s )+ CO 2( g ) leftharpoons 2 CO ( g ) Kp=((p CO )2/(p CO 2)) Here, p CO =8 atm and p CO 2=4 atm Therefore, Kp=((8)2/4)=(64/4) KP = 16 atm

Q. For the reaction
$C (s) + C O_{2} (g) 2 CO (g)$
the partial pressure for $C O_{2}$ and $CO$ are $4$ and $8$ atm respectively. $K_{p}$ for the reaction is

1 atm

5 atm

2 atm

16 atm

Key Idea For the reaction
$C (s) + C O_{2} (g) ⇌ 2 CO (g)$
$K_{p} = \frac{( p _{CO} ) ^{2}}{( p _{C O_{2}} )}$
Here, $p_{CO} = 8 a t m$ and $p_{C O_{2}} = 4 a t m$
Therefore, $K_{p} = \frac{( 8 ) ^{2}}{4} = \frac{64}{4}$
$K_{P} = 16$ atm
