Rate of reaction r = k [ A ] * [ B ]²      =  10⁻² mol/L/sec  initially

When half the reactants are consumed, the concentrations become half, assuming that solution / water remains same = 1 liter.

   rate of reaction now = k [ A ] /2  * ( [ B ] /2 )²  = 10⁻² / 8  mol/L/sec
                             = 1.25 * 10⁻³ mol /L /sec
