Is it possible for a reaction to have a large equilibrium constant but small forward and reverse rate constants?
emmainna [20.7K]

The equilibrium constant K and the forward rate constant k1 and backward rate constant k2 has the following relation:

K = k1 / k2

 

So from the equation, we can say that yes it is possible to have large K even if k1 is small given that k2 is very small compared to k1: (k2 very less than 1)

<span>k2 << k1</span>

REY [17]

Answer:

pH = 4.34

Explanation:

pH= -1/2(logKa) -1/2(log C)

= -1/2( log 5.98*10^-8) -1/2(log 0.0353)

=-1/2(-7.22)-1/2(-1.45)

=3.61+0.725= 4.34
