Hello students, 0 .225 molar of c6h5 in aqua solution produces c6h5nh3 positive plus oh negative.
00:16
At time t, the concentration of c6h5 and h2 decreases to 0 .225 minus x.
00:28
X is the concentration of the ions produced.
00:35
Kb for this reaction is equal to the concentration of both the ions of the products which is x multiplied with x divided by the concentration of the reactant which is 0 .225 minus x.
00:55
Kb for the reaction is 3 .9 multiplied.
01:00
With 10 to power minus 10 which is equal to x square 0 .225 minus x.
01:13
Solving the equation, x comes out to be 9 .3 multiplied with 10 to power minus 6 molar.
01:25
So we can say that the concentration of c6h5 and h3.
01:35
Is equal to the concentration of oh negative ions and the concentration of both of them is 9 .3 multiplied with 10 to power minus 6 molar.
01:51
Substituting the values of x in the concentration of reactant, that is c6h5 and h2, which is equal to 0 .22525.
02:08
Minus x...
