For the reaction C2H5COOC2H5 + H2O → C2H5COOH + C2H5OH, find the concentration of if the rate constant k=0.2 and the rate of the reaction is 0.39 s-1.

For the reaction C2H5COOC2H5 + H2O → C2H5COOH + C2H5OH, find the concentration of if the rate constant k=0.2 and the rate of the reaction is 0.39 s-1. Correct Answer C2H5COOC2H5

The reaction C2H5COOC2H5 + H2O → C2H5COOH + C2H5OH is a pseudo first order reaction and follows first order kinetics with rate law R=k. Given, rate of the reaction R=0.39 s-1 and rate constant k=0.2 So, 0.39 = 0.2 × =1.95 M.

For the reaction, A = X + Y, the respective concentrations are CA, CX and CY. The forward reaction rate constant is kf and the backward reaction rate constant is kb. Choose the correct statement from the following:
P. At equilibrium, kf CA > kB CxCy
Q. If the reaction is irreversible than, kb CXCY = 0

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 reaction temperature. 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 same volume. Then the order of this reaction is

The concentration of oxygen at the inner surface of the vessel is maintained at a level C depending on the pressure in the vessel, while the concentration at the outer surface is reduced to zero by the escape of oxygen to the surroundings. A steady state will eventually be reached when the concentration everywhere reaches a constant value.
