a) For a reaction where Kc >> 1, the initial concentration of reactant is 0.125 M.
When equilibrium has been achieved, this concentration will have changed
by only a negligible amount
b) For a chemical reaction where Kc ≈ 1, , there will be significant concentrations
of both reactant and product species when equilibrium has been achieved
c) For a reaction with a where Kc << 1, the initial concentration of reactant is 0.00671 M.
When equilibrium has been achieved, this concentration will have been reduced by only a very
small amount
d) A catalyst can reduce the time a given reaction takes to reach equilibrium, but does not change
the resulting equilibrium concentrations
