Name the slowest step that determines the rate in a complex reaction

Assertion : Complex reaction takes place in different steps and the slowest step determines the rate of reaction. Reason : Order and molecularity of a reaction are always equal.

Assertion: Order and molecularity of a reaction are always equal. Reason: Complex reactions take place in steps and slowest step determines the reaction order.

What is the rate determining step of a reaction ?

S_(N^(1)) reaction is a first order nucleophilic substitution e.g. CH_(3)-overset(CH_(3))overset(|)underset(CH_(3))underset(|)C-Br+H_(2)Oto CH_(3)-overset(CH_(3))overset(|)underset(CH_(3))underset(|)C-OH+HBr The concentration of nucleophile does not appear in the rate law expression. Reaction rate k[RX] In a mulptistep organic reaction , the rate-limiting step is the slowest step . Rate determining step is represented by the following energy level diagram: A reaction energy level diagram for an S_(N^(1)) reaction .The rate limiting step is spontaneous dissociation of an alkyl halide to give a carbocation intermediate: In S_(N^(1)) reaction the hybridization changes in rate determination step. Select the correct change among the following:

Which of the following statements are correct: (i) law of mass action and rate law expressions - are same for single step reaction (ii) the slowest step of a complex reaction gives the order of the complex reaction (iii) both order and molecularity have normally a maximum value of 3 (iv) m olecularity of a com plex reaction A + 2B to C is 3
