Ahome water softener has 75 000 cm3 of ion exchange resin with a capacity of 39 kg/m2 the occupants use 1800 l/day of water containing 0.24 mg/cm of hardness as caco3. if they want to soften the water to 78 mg/l as caco3, what percentage of water should bypass the unit? when will the unit need to be regenerated? (

Consider the reaction of a(g) + b(g) + c(g) => d(g) for which the following data were obtained: experiment initial [a], mol/l initial [b], mol/l initial [c], mol/l initial rate, mol/l. s 1 0.0500 0.0500 0.0100 6.25 x 10^-3 2 0.100 0.0500 0.0100 2.50 x 10^-2 3 0.100 0.100 0.0100 1.00 x 10^-1 4 0.0500 0.0500 0.0200 6.25 x 10^-3 what is the rate law for the reaction?
