An equimolar mixture of `CO_(2 (g))` and `CF_(4 (g))` was taken in an empty flask at a particular temperature. These gases reacts as: `CO_(2 (g)) + CF
An equimolar mixture of `CO_(2 (g))` and `CF_(4 (g))` was taken in an empty flask at a particular temperature. These gases reacts as:
`CO_(2 (g)) + CF_(4 (g)) hArr 2 COF_(2 (g))`
After this , mixture attains equilibrium and mole fraction of `COF_(2 (g))` was found to be `0.2`, then
Which of the following will increase concentration of `COF_(2 (g))` at equilibrium
A. decrease in temperature
B. increase in total pressure
C. Addition of inert gas at constant pressure
D. A and B both
1 Answers
Correct Answer - D
For increasing concentration of `COF_(2 (g))` at equilibrium
(A) Reaction is exothermic in forward direction hence, decrease in temperature, increase concentration of `COF_(2 (g))` at equilibrium.
(b) Total pressure increase, volume decreases and hence concentration increases.
