Question

Consult your textbook or other resources for mathematical treatment and graphical analysis of experimental data of concentration versus time for disappearance of a reactant [A] in a reaction. Match each linear graph shown below with that expected if the reaction is (a) zero, (b) first order, and (c) second order with respect to [A] Graph 1 = Represents first order kinetics according to [n] = [A_0]e^-kt Graph 2 = represents zero order according to [A_0] - [A] = K_0t graph 3 = represents 2nd order according toK_2 = 1/t [1/a - x - 1/a] 1/a - x = 1/a + K_2 t Explain how the value of the pseudo-rate constant k' can be calculated from the appropriate the linear graph shown above for a first-order reaction.

Explanation / Answer

Pseudo rate caonstant can be calculated from the graph shown for a first-order reaction by taking negative of the slope.
k' = -(slope)
