Zero order Reaction

Write the rate equation, integral rate constant and half life dependence with initial concentration for zero order and second order reactions.

Which of the following is correct for zero and first order reactions respectively, where 'a' is initial concentration of the reactant ?

The order of reaction can never be zero.

Molecularity is always a whole…………… while the order of reaction may be……………, ……………, ………………., or even zero.

What would be the effect on the rate of reaction due to the four-fold increase in a reactant concentration, if the order of reaction were the following: (a) Zero order , (b) First order ( c) 1//2 order , (d) Fourth order

Write units of rate constant for zero order and for the second order reactions if the concentration is expressed in mol L^(-1) and time in second.

Write the rate law expression for the reaction A+B+C to D +E , if the order of reaction is first second and zero with respect to A, B and C, respectively.

The order of reaction is an experimentally determined quanity. It may be zero, poistive, negative, or fractional. The kinetic equation of nth order reaction is k xx t = (1)/((n-1))[(1)/((a-x)^(n-1)) - (1)/(a^(n-1))] …(i) Half life of nth order reaction depends on the initial concentration according to the following relation: t_(1//2) prop (1)/(a^(n-1)) ...(ii) The unit of the rate constant varies with the order but general relation for the unit of nth order reaction is Units of k = [(1)/(Conc)]^(n-1) xx "Time"^(-1) ...(iii) The differential rate law for nth order reaction may be given as: (dX)/(dt) = k[A]^(n) ...(iv) where A denotes the reactant. The half life for a zero order reaction equals

The rate constant for zero order reaction is where c_(0) and c_(t) are concentration of reactants at respective times.

What is meant by order of a reaction being zero?
