WebReaction # [A] [B] [ C] Rate 1 1.00E-04 Determine the order with respect to each of the reactants [A],[B] and [C] and then the rate constant k' using the data below. WebExplanation: In order to find the rate constant of the reaction we need to analyze the data given in different trials. In trials 1 and 2 concentration of A is kept constant and that of B is doubled. We can observe that the rate of the reaction has not changed. This proves that changing the concentration of B has no impact on the rate of the ...

WebThe constant which defines the relationship between the molar concentration of the reactants and the rate of the chemical reaction is known as the rate constant. The rate constant is symbolized as k. Units of rate constant: Rate constant is dependent on the temperature. For zero-order reaction, rate constant's unit is mol L-1 s-1. For first ... WebRearranging the rate equation, the value of the rate constant ‘k’ is given by: k = Rate/ [A] x [B] y. Therefore, the units of k (assuming that concentration is represented in mol L -1 or M and time is represented in seconds) can be calculated via the following equation. k = (M s-1)* (M-n) = M(1-n) s-1. The units of the rate constants for ...
