Question

The irreversible reaction (A + B ? R + S) was carried out in a batch reactor in solution at 25°C. The obtained concentration-time data is shown in the table below. Time (min) 0 75 150 225 300 375 450 $C_A$ (mol/dm$^3$) $50.0 \times 10^{-3}$ $38.0 \times 10^{-3}$ $30.6 \times 10^{-3}$ $25.6 \times 10^{-3}$ $22.2 \times 10^{-3}$ $19.5 \times 10^{-3}$ $17.4 \times 10^{-3}$ The initial concentration of B was 2.5 mol/dm$^3$. In a separate experiment, the reaction order with regards to B was found to be first order. a) Use the differential method to determine the reaction order with respect to A and reaction rate constant. All steps of the method must be included. b) Use the integral method to determine the reaction order with respect to A and reaction rate constant. All steps of the method must be included. For this question provide working.
