Learn how to find the rate law and rate constant (k) in a few simple steps with this video. a common exam question for chemistry students.
How To Calculate Rate Constant K Of Reaction Rates Youtube This chemistry video tutorial explains how to determine the units of the rate constant k for a first order reaction, second order reaction, and a zero order. From this equation, a general formula for the units of k is obtained which is: k units = m1 n · t 1. where n is the reaction order. for example, let’s say we want to determine the units of the rate constant for third order reactions. n = 3, and therefore, k units = m1 3 · t 1 = m 2 · t 1. if the time is seconds, then the units will be:. The rate constant k and the exponents m, n, and p must be determined experimentally by observing how the rate of a reaction changes as the concentrations of the reactants are changed. the rate constant k is independent of the concentration of a, b, or c, but it does vary with temperature and surface area. Determine the numerical value of the rate constant k with appropriate units. the units for the rate of a reaction are mol l s. the units for k are whatever is needed so that substituting into the rate law expression affords the appropriate units for the rate. in this example, the concentration units are mol 3 l 3.

The values of the reaction orders m and n, and rate constant k are determined from the experimental data using a three part process: in step 1, the value of m is determined from the data in which [no] varies, and [o 3] is constant. in trials 3, 4 and 5, [no] varies while [o 3] remains constant. when [no] doubles from trial 3 to 4, the rate. B the rate law for the reaction is therefore \( rate = k \left [n {2}o {5} \right ]\) calculating the rate constant is straightforward because we know that the slope of the plot of ln[a] versus t for a first order reaction is −k. we can calculate the slope using any two points that lie on the line in the plot of ln[n 2 o 5] versus t.
