Dissociation of a salt A(2)B(3)(aq) in w...

Dissociation of a salt `A_(2)B_(3)(aq)` in water follows first order kinetics in terms of concentration of `[A_(2)B_(3)]` as `A_(2)B_(3)(aq)to2A^(+3)(aq)+3B^(2-)(aq)`. Starting from t=0, solution is taken out at different instant and its osmotic rise is measured. From the given data calculate abcd.
ab=`t_(3//4)` of the dissociation of `A_(2)B_(3)` in water in minutes.
cd= Osmotic pressure in Pascal after 20 min.density of solution is 1 g`//`mL.
`{:(,"Given data :",t=0,t=10 min,),(,"osmotic rise",2 mm,6 mm,):}`
