Identity the graph (A or B), represents the change in concentration of reactant with time.

Rate of a reaction is the change in concentration of reactant or product per unit time.what does the slope of the graph represent, variation In the concentration vs time for a zero order reaction?

Assertion :In any reaction, the rate of disappearance of a reactant is same as the rate of reaction. Reason: Both rate of reaction and rate of disappearance of a reactant represent decrease in the concentration of the reactant per unit time.

In ____order reaction the rate of a reaction does not change with the concentration of the reactants.

Assertion :The rate of the reaction, A rarr B is the rate of change of concentration of a reactant or a product. Reason: Rate of reaction remains constant duringthe course of reaction.

Zero order reaction means that the rate of a reaction is independent of the concentration of reactants. Write an example for a zero order reaction.

Assertion :For a first order reaction, the concentration of the reactant decreases exponentially with time. Reason: Rate of reaction at any time depends upon the concentration of the reactant at that time.

Write an experiment to prove that concentration of reactants affect the rate of reacions ?

Which of the following statement true for molecularity of a reaction? It is sum of exponents of the molar concentration of the reactants in the rate equation, It may have a fractional value, It is the number of molecules of the reactants taking part in a single step chemical reaction, It is determined experimentally

Following graph is a plot of the rate of reaction concentration of the reactant. What is the order of the reaction.

Rate of a reaction is the change in concentration of any one of the reactants or any one of the products in unit time. Define order of a reaction.
