An evaporator is a unit operation that concentrates a liquid solution by evaporating pure water as vapour. A liquid stream flowing at a rate of 500 kg/h containing 25% by mass NaOH is fed to an evaporator, and the concentration of the resulting liquid output is 40% NaOH. Calculate the rate of product formation (kg/h) and vapour production (kg/h) at steady state. 31.2 kg/h and 18.7 kg/h 18.7 kg/h and 31.2 kg/h 187 kg/h and 312 kg/h 312 kg/h and 187 kg/h
