Since only concentration of CH 3 Br would change during the reaction, the rate would only change due to the changes in the CH 3 Br reaction. Because the reaction is first order with respect to CH 3 Br, the kinetics would appear to be first order with a new "pseudo-first order rate constant", k'. The value of this rate constant would depend on the value of the overall rate constant, k, and the initial fixed concentration of OH -.

Pseudo-First order A very important case is that of pseudo-first order kinetics. As a result, the order of reaction becomes one. Pseudo-first order kinetics is an important example. This article learned about the definition of pseudo first-order reaction and examples of pseudo first-order reaction. What is the difference between first-order and pseudo first-order reactions?

Ans: A first-order reaction is when the concentration of only one reactant changes or in which the reaction rate is proportional to the first power of the concentration of the reactant.

The reactions which are not truly of the first order but under certain conditions become reactions of the first order are called pseudo first-order reactions. How do you solve a pseudo first-order reaction? Ans: In any reaction, if one of the components is in excess quantity, then the concentration change will be constant. The reaction is belonging to pseudo first order reaction. What is pseudo first-order reaction? Ans: The reactions apparently seem to be of higher order but under certain circumstances behave as first-order reactions referred to as pseudo first-order reaction.

For the hydrolysis of methyl acetate in an aqueous solution, the above-tabulated results were obtained: Show that it follows pseudo-first order reaction as the concentration of water remains constant. What is the pseudo rate constant? Does temperature affect the pseudo rate constant? Ans: The reaction rate was found to increase with increasing temperature, indicating that a highly solvated transition state was formed during the reaction.
