Question
For a general reaction A → B, plot of concentration of A vs time is given in figure. Answer the following question on the basis of this graph.
(i) What is the order of the reaction?
(ii) What is the slope of the curve?
(iii) What are the units of rate constant?

Solution
(i) Zero order reaction
(ii) [R] – [R]0 – kt
∴ Slope = – k
(iii) `(mol^-1L)/(s^-1)` = k[A]0 or k = mol–1 Ls–1

Molecularity of a reaction _____________.
Which of the following statements is not correct about order of a reaction.
For which type of reactions, order and molecularity have the same value?
Why is the probability of reaction with molecularity higher than three very rare?
Why molecularity is applicable only for elementary reactions and order is applicable for elementary as well as complex reactions?
Assertion: Order of the reaction can be zero or fractional.
Reason: We cannot determine order from balanced chemical equation.
Assertion: The enthalpy of reaction remains constant in the presence of a catalyst.
Reason: A catalyst participating in the reaction, forms different activated complex and lowers down the activation energy but the difference in energy of reactant and product remains the same.
