The partial pressure of CH3OH,CO and H2 ...

The partial pressure of `CH_3OH,CO and H_2` in the equilibrium mixture for the reaction `CO+2H_2 hArr CH_3OH "at" 427^@C` are 2.0 ,1.0 and 0.1 atm respectively. The value of `K_p` for the decomposition of `CH_3OH` to CO and `H_2` is

A

`1 xx 10^(2)` atm

B

` 2 xx 10^(2) atm ^(-1)`

C

`50 atm ^(2)`

D

`5 xx 10^(-3) atm^(2)`

Text Solution

Verified by Experts

The correct Answer is:
D
` CH_(3) OH to CO + 2H_(2)`
`([H_(2)]^(2) [CO])/([CH_(3)OH]) = (0.1 xx 0.1 xx 1)/( 2) = (0.01)/(2) = (01 xx 10 ^(-3))/(2)`
`= 5 xx 10 ^(-3)`
