Question

A vessel at 1000 K contains CO₂ with a pressure of 0.5 atm. Some of the CO₂ is converted into CO on the addition of graphite. If the total pressure at equilibrium is 0.8 atm, the value of K is 

(a) 1.8 atm 

(b) 3 atm 

(c) 0.3 atm 

(d) 0.18 atm

Answer 1

The correct option is (a) 1.8 atm.

Explanation:

K_p depends upon the partial pressure of reactants and products so first calculate their partial pressure and then, calculate K_p,
