The liquid-phase irreversible reaction A>B+C is carried out in an ideal constant volume batch reactor. The concentrations of specie A are recorded as a function of the time and appear below. The initial concentration of A is 20mol/dm3. Determine the reaction order and reaction rate constant, using concentration units of mol/dm3 and a time unit of minutes. reaction order =0 reaction rate constart =0.2 reaction order =2 reaction rate constart =0.1 reaction order =1 reaction rate constant =0.2 reaction order =0 reaction rate constant =0.1
