Question

Choose all of the following statements about the equilibrium constant K that are true:
(a) If the K value for a reaction is > 1 then Go must be negative for this reaction
(b) A large value for K implies there is a strong driver for the reaction to proceed in the forward direction and the reaction will be rapid
(c) If Q is greater than K at a given time of reaction, then the reaction will be moving to the side of more reactants
(d) Q can never exactly equal K
(e) None of these is true
help me!

Answer 1

a) Look at Go = -RTlnK. If K >1 what's the sign of Go?
b)It DOES imply a strong driver for the reaction BUT ".....and the reaction will be rapid" it has nothing to do with the speed. We can have huge K values but the reaction proceeds so slow it will take centuries to complete.
c). If Q>K, that means products are too high and reactants are too low, so ....
d)Of course Q can equal to K.
e. ..
