Chemical Equilibrium Help

[minus]

Can anyone please help me on these chem equilibrium questions. I just want to make sure if they are correct or not.

 

1. A chemical system in equilibrium will

a. form more products if the the temperature is increased

b. have a specific ratio of product to reactant concentrations

c. not have any precipitates

d. represent a spontaneous chemical process

 

is the answer b? i think it makes the most since. i know it is definitely not C or D. and i think A. depends on whether it is an exothermic or endothermic reaction.

2. A reaction has a very large equilibrium constant of 3.3x10^13. Which statement is NOT true about this reaction?

 

a. the reaction is very fast

b. the reaction is essentially complete

c. the equilibrium constant will change if the temperature changes.

d. the products will react to yield very little reactants.

 

ok for this one i think the answer is a.

b and c is definitely true. and for d since k > 1 then it'll shift right because the products are favored so i think that is also true. so that leaves a as being false
