Zero-order reactions always have rate constants that are represented by molars per unit of time. Higher order reactions, however, require the rate constant to be represented in different units. True. When using the rate function \( rate = k[A]^n \) with n equal to zero in zero-order reactions.

order reaction from a plot of [A] versus t by the variation in the time it takes the concentration of a reactant to change by half.

I will use the one with the guard For a first order reaction, as shown in the following figure, the plot of the logrithm of [A] versus time is a straight line with k = - slope of the line. Other graphs are curved for a first order reaction. For a second order reaction, as shown in the following figure, the plot of 1/[A] versus time is a straight line with k = slope of the line So if second order reaction is observed then graph of 1/a-x v/s t gives straight line with slope K and intercept 1/a at t = 0.

The order of reaction is simply n. In this case, the order of reaction with respect to reactant B is 1. The rate order is calculated for one reactant only. Now, we need to calculate the rate order with respect to the other reactant. The order of reaction with respect to reactant A is calculated as follows: The overall order of reaction
