1) The exothermic formation of ClF3 is represented by the equation: Which of the following will increase the quantity of ClF3 in an equilibrium mixture of Cl2, F2 and ClF3? A) Adding $F_{2}$ B) Increasing the volume of the container C) Removing $Cl_{2}$ D) Increasing the temperature Answer: Option AExplanation:The reaction given is an exothermic reaction thus according to Le chatalier's principle lowering of temperature, the addition of F2 , and Cl2 , favour the forward direction and hence the production of ClF3.
