1) <span>Chemical reactions are always spontaneous when CHANGE IN H is negative and CHANGE IN S is negative</span>False
2)The driving force of a reaction is the change in kinetic energy.
True
3) In the reaction so2cl2 double arrows s02+cl2 heat is evolved. What happens when chlorine (Cl2) is added to the equilibrium mixture at constant volume?
b. The temperature of the system decreases.
4) In a reversible reaction, two substances are in equilibrium if the concentration of each increases by the same amount but the equilibrium constant remains unaffected.
True
5) A numerical value of the ratio of products to reactants, only at a specified temperature is called a(n)
b. equilibrium constant
6)At equilibrium,
a. all reactions have ceased.
The correct answer is a Forward reaction to slow.
According to Le Chatelier's principle as the reactant decrease so the reaction should go leftward and this is called backward or reverse reaction so the reverse reaction will be fast to achieve equilibrium and the forward reaction will be slow.
