Question

The following reactions start at equilibrium. A stress is added and the position of equilibrium shifts. After the indicated stress is added which of the following reactions will proceed towards products? The added stress is the part listed inside the braces {} A.)Cl2(aq) + 2NaI(aq) I2(aq) + 2NaCl(aq) {and NaCl(aq) is removed} B.)Pb(NO3)2(aq) + 2KI(aq) PbI2(s) + 2KNO3(aq) {and KNO3 is added} C.) Cl2(aq) + 2NaI(aq) I2(aq) + 2NaCl(aq) {and NaI(s) is added. Note: adding NaI(s) is the same as increasing NaI(aq)} Not A, Not B, Not C alone

Explanation / Answer

as you see A) in the first reaction product (NaCl) is removed so reaction will try to nullify this effect and will move toward products(forward reaction) B) in this reaction as product is added that is KNO3 so reaction will move backward towards reactants C) As reactant NAl is added so reactant concentration will became high and reaction move toward products(forward reaction) conclusion: answers: (A),(C) i hope it would help you thanks
