What is the rate of a reaction if the value of k is 3 and A and B are each 2 M Rate kA2B?
The rate of the reaction is determined by the rate law, which is typically expressed as Rate = k[A]^m[B]^n, where m and n are the orders of the reactants. If k = 3, A = 2 M, and B = 2 M, and the reaction is kA^2B, then the rate would be 3 x (2)^2 x (2) = 24 M/s.
What is the rate law for the following reaction A plus 2B creates C plus D 1 rate kAB2 2 rate kA2B 3 rate kA2 B2 4 rate kAB?
A + 2 B ==>C + Drate = k[A][B]^2 if this is an elementary step. If not, you cannot determine rate equation.So, #1 would be the best answer, i.e. rate = kAB2 but the square only applies to B and not to A, so it isn't really written correctly.
What units must the rate constant have based on the rate law, and can you provide an example of how to calculate it?
The rate constant must have units that make the rate equation balanced. For example, if the rate law is rate kA2B, the rate constant k must have units of M-2 s-1. To calculate the rate constant, you can use experimental data and the rate law equation to solve for k.
