The exothermic formation of ClF3 is represented by the equation : Cl2 (g) + 3F2 (g) 
2ClF3 (g) ; DrH = – 329 J
which of the following will increase the quantity of ClF3 in an equilibrium mixture of Cl2 , F2 and ClF3.
A
Adding F2
B
Increasing the volume of container
C
Removing Cl2
D
Increasing the temperature
Answer
Adding F2
Explanation
Solution
CI2(g) + 3F2(g) 
2CIF3(g) ; DH = – 329 kJ.
Favourable conditions:
(i) Decrease in temperature, (ii) Addition of reactants,
(iii) Increase in pressure i.e., decrease in volume.
