Analyse the given graph,drawn between concentration of reactant vs. time.
(a)Predict the order of reaction.
(b)Theoretically, can the concentration of the reactant reduce to zero after infinite time?Explain.

If the concentration of the reactants is increased, the rate of reaction for first order-

For a reaction , a graph was plotted between reactant concentration c and time as shown in the figure below. Identify the order of the reaction with respect to the reactant. Can the concentration of the reactant be theoretically zero after infinite time?

The concentration of reactant decreases linearly with time. What is the order of the reaction ?

For a first order reaction, the concentration of reactant :

A reactions is of second order with respect to a reactant. How is the rate of reaction affected if the concentration of the reactant is reduced to half?
