What affects the reaction equilibrium between S and P? What affects the reaction rate of the conversion from S to P? What aspect of a reaction can an enzyme alter?

Homework Answers

Answer #1

(i) Addition of substrates or products can affect the equilibrium between S and P.

Note: If you add substrate S to the system, the equilibrium shifts towards P (right side), and if you add product P to the system, the equilibrium shifts towards S (left side).

(ii) A catalyst can affect the reaction rate of the conversion from S to P.

Note: A positive catalyst can increase the rate of reaction, whereas a negative enzyme can decrease the rate of a reaction.

(iii) The activation energy of the reaction or pathway of the reaction will be altered by the enzyme.

Reaction (i) Pb2+(aq) + 2 Cl-(aq) ⇌ PbCl2(s) If NaOH is added to reaction (i), a second precipitation reaction will occur: Reaction (ii) Pb2+(aq) + 2 OH-(aq) ⇌ Pb(OH)2(s) The important aspect of this is that the two reactions take place within the same container (just because we draw them separately on paper does not mean they are separate inside in the container). Thus, reaction (i) and (ii) are coupled at the molecular level by a common chemical species that...

The equilibrium constant (Kp) for the reaction below is 70.0 at 32 °C: NH4HS(s) <---> NH3(g) + H2S(g) A sample of NH4HS(s) is placed in an evacuated container and allowed to come to equilibrium. (You should calculate what the P is of all gases at this point) The partial pressure of H2S is then increased by the addition of 1.00 bar of H2S, and the system responds accordingly( shifts?). Calculate the partial pressure of every gas after such shift.
