The instantaneous rate of reaction 2A+B to C +3D is given by

Assertion: The instantaneous rate of reaction can be studied in chemical kinetics. Reason: Inoic reactions occur instantaneously.

The rate of reaction A+Bto Products is given by Rate =k[A]^(1//2)[B]^(2) . What are the units of the rate constant ?

The rate law of reaction A+2Bto product given by r=K(A)^(2)(B)^(1) . If A is taken in excess the order of the reaction will be :-

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. The rate of formation of SO_(3) in the following reaction, 2SO_(2)+O_(2)rarr 2SO_(3) is 10 g sec^(-1) The rate of disappearance of O_(2) will be:
