How do you explain rate law?
Well, a rate law is a mathematical expression that shows how the rate of a chemical reaction depends on the concentration of those reactants. And sometimes, the rate is dependent on the concentration of the reactants, and sometimes it is not.
What is the rate law illustrate your answer?
The rate law (also known as the rate equation) for a chemical reaction is an expression that provides a relationship between the rate of the reaction and the concentrations of the reactants participating in it.
How do you know if a reaction is first or second order?
Initial Rate (M/s) Determine the reaction order and the rate constant. If a plot of reactant concentration versus time is not linear but a plot of 1/reaction concentration versus time is linear, then the reaction is second order.
What is rate law and how is it expressed?
Rate law is the expression in which reaction rate is given in terms of molar concentration of reactants with each term raised to some power, which may or may not be same as the stoichiometric coefficient of the reacting species in a balanced chemical equation.
What is rate law explain with an example?
A rate law relates the concentration of the reactants to the reaction rate in a mathematical expression. For example, the rate law Rate=k[NO]2[O2] Rate = k [ NO ] 2 [ O 2 ] describes a reaction which is second-order in nitric oxide, first-order in oxygen, and third-order overall.
How do you derive a first order rate law?
rate of reaction = v = -d[A]/dt = d[B]/dt = k1[A] where k1 is the 1st-order rate constant for the forward reaction, [A] is the reactant concentration, and [B] is the product concentration. The rate of the reaction (or its velocity v) is given either by the rate of disappearance of [A] or appearance of [B].
What is integrated rate law method?
An integrated rate law is an equation that expresses the concentrations of reactants or products as a function of time. An integrated rate law comes from an ordinary rate law.
How do you derive a first order reaction?
To test if it the reaction is a first-order reaction, plot the natural logarithm of a reactant concentration versus time and see whether the graph is linear. If the graph is linear and has a negative slope, the reaction must be a first-order reaction.
