What happens in a dynamic equilibrium exits in a reaction?

Answer 1

Naomi Aronson

#"Option (b) is the answer I would choose......."#

Think about the improbable response:

#A+BrightleftharpoonsC+D#

There is a forward rate at this time.

#"Rate forward"=k_f[A][B]#

Additionally, there is a reverse rate.

#"Rate backwards"=k_r[C][D]#.

The equality of FORWARD and REVERSE rates is what is meant to be specified by the condition of chemical equilibrium, not the end of chemical change.

#"Rate forward"="Rate backward"#, and so.........

#k_f[A][B]-=k_r[C][D]#.......and so......

#k_f/k_r=([C][D])/([A][B])#

We commonly call the #k_f/k_r# quotient as #K_"eq"#, the # "thermodynamic equilibrium constant"#, which is usually independent of temperature.

Noah Aldrich

In a dynamic equilibrium, the forward and reverse reactions occur at the same rate, leading to a constant concentration of reactants and products.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
