Batch reactor problems, calculation examples

Problem

Consider the elementary reaction A → B + C which occurs in liquid state and ideal batch reactor at constant temperature. Determine the time required for the concentration of A to become half of the its initial concentration.
reaction rate constant,K = 0.1 /sec

Assumptions

Due to constant temperature, K is constant.
Due to liquid phase reaction, we can assume total volume of liquid (which reaction occurs) is constant (V=constant).

You should know how molar balance is applied to batch a reactor.

solution

rA - reaction rate
V - total volume of liquid
t - time
C - concentration
NA - moles of A
