Heating the solution.Explanation / Answer
(a)
* Heating the solution favours endothermic reaction i.e products.
* Lowering the concentration of products i.e.Br- fovours products.
* Remvoing products i.e silver ions favours products.
* Adding HBr increase the concentration of Br-, hence it favours the formation of reactants.
* Adding solid AgBr does not affect the equilibrium, as the concentration of solids is constant.
(b)
* Decrease in volume favours towards less number of gas moles i.e products side in this case.
* Increase in volume favours towards more number of gas moles i.e reactants side in this case.
* Addition of catlyst does not alter the equilibrium, it just helps the reaction to reach equilibrium faster.
* Addition of chlorine increases the concentration of reactants which favours the formation of products.
* Removal of PCl3, decrease the concentration of reactants, which favours the formation of reactants.
