What are the methods used to determine the order of a reaction?

The method of determining the order of a reaction is known as the method of initial rates. The overall order of a reaction is the sum of all the exponents of the concentration terms in the rate equation.

How do you determine the rate of a faster reaction?

Temperature. Usually reactions speed up with increasing temperature. Physical state of reactants. Powders react faster than blocks – greater surface area and since the reaction occurs at the surface we get a faster rate.

How do you determine the order of a reaction experimentally?

Either the differential rate law or the integrated rate law can be used to determine the reaction order from experimental data. Often, the exponents in the rate law are the positive integers: 1 and 2 or even 0. Thus the reactions are zeroth, first, or second order in each reactant.

What tells how fast or slow the reaction occurs?

reaction rate, in chemistry, the speed at which a chemical reaction proceeds. It is often expressed in terms of either the concentration (amount per unit volume) of a product that is formed in a unit of time or the concentration of a reactant that is consumed in a unit of time.

How do you calculate the rate of a chemical reaction?

For a reaction of A → B the reaction rate is (change of concentration)/time. If plotted on a graph, the concentration of A would decrease over time and the concentration of B would increase. The gradient of the graph indicates the rate of reaction – the steeper the gradient the faster the rate of reaction.

How do you calculate the rate of an enzymatic reaction?

The Michaelis-Menten equation calculates the reaction velocity by multiplying substrate concentration by maximum velocity (Vmax) and dividing it by the sum of Km and substrate concentration.

What is meant by the rate of a reaction?

What is the unit of rate of reaction?

Reaction rates are usually expressed as the concentration of reactant consumed or the concentration of product formed per unit time. The units are thus moles per liter per unit time, written as M/s, M/min, or M/h.
