Question

The exothermic formation of `CIF_(3)` is represented by the equation:
`CI_(2)(g)+2F_(2)(g)hArr2CIF_(3)(g),Delta_(r)H=-329J`
which of the following will increase the quantity of `CIF_(3)` in an equilibrium mixture of `CI_(2),F_(2) "and" CIF_(3)`.
A. Adding `F_(2)`
B. Increasing the volume of container
C. Removing `CI_(2)`
D. Increasing the temperature

Answer 1

Correct Answer - A
`CI_(2)(g)+3F_(2)(g)hArr2CIF_(3)(g),DeltaH=-329KJ`. Favourable conditions:
(i) Decrease in temperature. (ii) Addition of reactants, (iii) Increase in pressure i.e., decrease in volume.
