Specific rate constant for a I order reaction depends upon : Temperature Time Concentration of reactants Concentration of products
Reaction order of a radioactive disintegration reaction is zero one two three
A photosensitive substance is one which: Increases the rate of photochemical reaction. Decreases the rate of a photochemical reaction. Start a Photochemical reaction Stops a photochemical reaction.
In the reaction : 2A+B-->Product, if the active mass of B is made constant and that of A is doubled, Decreases two times Decreases four times Becomes double Increases four times
What changes by the use of catalyst in a reaction : Reaction product Equilibrium constant Heat of reaction Activation energy
Rate of a reaction is k[A]n[B]m, its order is : m+n m-n m n
Product obtained by the photolysis of water is : OH- + H+ H2+2OH- H2+ O2 H2O + H2O2
Quantum yield of photochemical reaction is : Always 1 Always greater than 1 Always less then 1 may be equal to, greater than or less then1
When the temperature of the reaction increased, the rate of the reaction also increased effectively increase in the energy of activation increase in the number of molecules increase in the number of effective collisions Decrease in the energy of activation
Rate constant of a reaction increases with the increase of which of the following factors : Temperature Concentration of reaction Pressure all the above
