Concept introduction:
- Zero-order reaction- for this, rate of reaction is independent of the concentration.
And the graph of zero order reaction is-

Concept introduction:
- The first order reaction is the one in which the rate is directly proportional to the concentration of one of the reactant.
And half-life is
Integral rate law for first order reaction is −

Concept introduction:
- The second order reaction is the one in which the rate is directly proportional to the square of the concentration of one of the reactant.
Integral rate law for second order reaction is −

- A. Determine the number of electrons in a system of cyclic conjugation (zero if no cyclic conjugation). B. Specify whether the species is "a"-aromatic, "aa"-anti-aromatic, or "na"-non-aromatic (neither aromatic nor anti-aromatic). (Presume rings to be planar unless structure obviously prevents planarity. If there is more than one conjugated ring, count electrons in the largest.) 1. A.Electrons in a cyclic conjugated system. 18 B.The compound is (a, aa, or na) a 2.
