In which of the following cases, does the reaction go farthest to completion ?
∵ higher the equilibrium constant , fastest the rate of reaction to completion.
The activation energy of a reaction is zero. The rate constant of the reaction …
is nearly independent of temperature. $ Ea = 0 \therefore K = A.e ^ { -Ea /RT } = A.e ^ \circ = A $
Which of the following is the fast reaction ?
$ 6 CO_2 + ^ 6 H_2 O \rightarrow C_6 H_{12} O_6 + 6 O_2 $
Oxidation of oxalic acid by acidified $ KMnO_4 $ is an example of autocatalysis. It is due to which of the following ?
$ Mn^{2+} $
What will be the order of the reaction if doubling the concentration of a reactant increases the rate by a factor of 4 and trebling the concentration of the reactant by a factor of 9 ?
2 $ 2 ^ n = 4 3^n = 9 $ $ \therefore n = 2 $
If the half time for a particular reaction is found to be constant and independent of the initial concentration of the reactants then reaction is of ...

Rate of chemical reaction can be kept constant...
none of the above
The one which is unimolecular reaction is
$ N_2 O_5 \rightarrow N_2 O_4 + { 1 \over 2} O_2 $
The rate of reaction for $Cl_3 C CHO + NO \rightarrow CHCl_3 + NO + CO $ is given by equation, $ rate = K[Cl_3 C CHO][NO] $ . If concentration is expressed in $ mole litre^{-1} $ , the unit of K are
$ litre mole^{-1} sec ^ {-1} $
