The correct statement are:
1. for an elementary reaction order and molecularity are same
2. Reactions having order and molecularity `lt3` are rate
3. Rate of reaction is decided by slowest step of mechanism
4. for a reaction `t_(1//2)` does not depend upon temperature
5. energy of activation for free radical combination is zero.

Give one example of the reaction where order and molecularity are the same. Mention any two factors that influence the rate of chemical reaction. If for the reaction

Statement: The elementary reaction is single step reaction and does not possess mechanism. Explanation: An elementry reaction has order of reaction and molecularity same.

Assertion (A) : The rate constant of a zero order reaction has same units as the rate of reaction. Reason (R ): Rate constant of a zero order reaction does not depend upon the units of concentration.

Complex Reaction || Molecularity || Difference between Molecularity and Order || Integrated Rate Law Equation for Zero Order Reaction

The rate and mechamical reaction are studied in chemical kinetics. The elementary reactions are single step reaction having no mechanism. The order of reaction and molecularity are same for elementary reactions. The rate of forward reaction aA + bBrarr cC+dD is given as: rate =((dx)/(dt))=-1/a(d[A])/(dt)=-1/b(d[B])/(dt)=1/c(d[C])/(dt)=1/d(d[D])/(dt) or expression can be written as : rate =K_(1)[A]^(a)[B]^(b)-K_(2)[C]^(c )[D]^(d) . At equilibrium, rate = 0 . The constants K, K_(1), K_(2) are rate constants of respective reaction. In case of reactions governed by two or more steps reaction mechanism, the rate is given by the slowest step of mechanism. For a gaseous reaction, the rate is expressed in terms of (dP)/(dt) in place of (dC)/(dt) or (dn)/(dt) where C is concentration, n is number of moles and 'P' is pressure of reactant. The three are related as:

Will the rate constant of the reaction depend upon T if the E_act (activation energy) of the reaction is zero?
