The following is a second order irreversible reaction: a+a 2b the rate constant is ki = 0.35 l/mol-min, and the initial concentration of a is 1.2 mol/l. find: i. the time at which the fractional conversion of a is 75%. ii. the concentration of a at the time found in parti. iii. the concentration of b at the time found in part ii. the following reaction is a second order irreversible reaction: 5. 2a + 3b β 2c i. derive an expression for the rate of change in the concentration of a as a function of reaction time, initial concentrations and a second order rate constant. solve this differential equation to yield an equation for fractional conversion of a as a function of time. ii. the rate constant is 0.02 l mmol-min, and the initial concentrations of a, b, and are 10 mmol/l, 10 mmol/l and 0 mmol/l, respectively. draw a plot (neatly and accurately) of the concentrations of a, b, and c with time for the first 10 minutes of the reaction. 13. the following autocatalytic reaction occurs: a+b 2b the reaction takes place in a reactor having an initial concentration of 10 mmol/l a and 1 mmol/l b. 90% of the a is converted in 22 minutes. the reaction is conducted again with twice the initial concentration of b. what length of time does this second reaction require for 90% conversion of a? the following second order reaction occurs: 14. a + 2bc the initial concentration of a is 11 mmol/l and the initial concentration of bis 13 mmol/l. the reaction has a second order rate constant of 0.012 l/mmol: min. what is the concentration of b 5.0 minutes after the reaction commences?
