Here is a question on General Chemistry, Chapter 14A. Icheck the solution for this, but not found. plz help me to do this A+B+heat C+D What will happen to the concentrations oa A,B,C,and D undereach of the following conditions? 1. A catalyst is added to the system, which is atequilibrium. 2. Either C or D is added to the system, which is initially atequilibrium. 3. Either C or D is removed from the system, which isinitially at equilibrium 4. either a or b is added to the system, which is initially atequilbrium 5. the system, which is initially at equilibrium, iscooled 6. the system which is initially at equilibrium, isheated Here is a question on General Chemistry, Chapter 14A.

Given reaction: A+B+heat C+D i) Catalyst is the species that enhances or decreases the rate ofthe reaction. Generally it will not interact with the reactants orproducts. So there is no affect of catalyst on the equilibrium. ii) When the products, either C or D is added to the system atequilibrium, then it shifts to left. So the reaction shifts to lefthand side. iii) When either C or D removed from the system, more products willbe formed. So the equilibrium shifts to right. iv) When A or B is added to the system at equilibrium , thereaction shifts to right. So more products are favored. v) Rising the temperature favors theendothermic reaction, the reverse reaction.Lowering the temperature favors the forward reaction. On on cooling the reaction shifts to right. vi) On heating the system at equilibrium , the reactionshifts to left.
