If the following rate constant, Kf, and the reverse rate constant, Kr, for a chemical reaction are NOT equal, which must be true.
a: The reaction will be unable to acheive equilibrium
b: Kf and Kr will become equal as equilibrium is approached owing to concentration changes.
c: Kf and Kr will become equal as equilibrium is approached owing to temperature changes
d: Kf and Kr will remain unequal bot rates will become equal owing to concentration changes
e: Kf and Kr will remain unequal but the rates will become equal owing to temperature changes
