MCAT Equilibrium

Chemistry Equilibrium

QuestionAnswer
Can equilibium constant (K eq) ever be negative? no
K(eq) < 1 means... reaction favors the reactants
K(eq) > 1 means... reaction favors the products
lowering temp favors... exothermic reactions
raising temp favors... endothermic reactions
Q > K(eq) means... the reacton procedes in the reverse
Q < K(eq) means... the reaction procedes forward
Exothermic reactions are located.... and ∆H is... on the product side; negative
Endothermic reactions are located... and ∆H is ... on the reactants side; positive
Adding a catalyst to a reaction that is already at equilibrium will have what kind of effect... adding a ( ) increases the rate of both the forward and reverse reactions equally, hoewever the equilibrium amounts will not change
In a reaction at equlibrium, if the volume is reduced, therefore increasing the pressure, a net reaction occurs favoring... the side with the smaller total number of moles
In a reaction at equlibrium, if the volume is expanded, therefore decreasing the pressure, the net reaction occurs favoring... the side with the greater total number of moles
What will happen to a reaction's equilibrium contsant K(eq) if the temp changes? The value of K(eq) is constant at a given temp therefore if the temp changes so does the K(eq)
