Rate constant for a first order reaction does not depend upo
Rate constant for a first order reaction does not depend upon reaction time, extent of reaction and the initial concentration of reactants ; but it is a function of reactiontemperature.
In a chemical reaction, the time required to reduce the concentration of reactant from 100 gm moles/litre to 50 gm moles/litre is same as that required to reduce it from 2 gm moles/litre to 1 gm mole/litre in the samevolume.
Then the order of this reaction is
If the time required to change the concentration of reactant
If the time required to change the concentration of reactant to half its original value is independent of the initial concentration, the order of reaction is
In a chemical reaction, repesented by, , it is observed that
In a chemical reaction, repesented by, , it is observed that the(i) rate of reaction increases by a factor of 4 on doubling the concentration of thereactant.
(ii) rate of reaction increases by a factor of 9 on trebling the concentration of thereactant.
Then the rate of the reaction is proportional to(where, CA = contentration of the reactant)
For a chemical reaction A ® B, the rate of the reaction is
For a chemical reaction A ® B, the rate of the reaction is 2 ´ 10-3 mol dm-3 s-1, when the initial concentration is 0.05 mol dm-3. The rate of the same reaction is 1.6 ´ 10-2 mol dm-3 s-1when the initial concentration is 0.1 mol dm-3. The order of the reaction is
For a __________ order chemical reaction, , the half life pe
For a __________ order chemical reaction, , the half life period is independent of the initial concentration of the reactant A
Time required for concentration of reactant to fall down to
Time required for concentration of reactant to fall down to its half value from original value is

If the time required for half change is inversely proportion
If the time required for half change is inversely proportional to the square of initial concentration and the velocity depends on the units in which the concentration term is expressed, then the order of reaction is
Half-life period for a first order reaction is __________ th
