Consider a reaction, aG + bH → Products. When concentration of both the reactants G and H is doubled, the rate increases by eight times. However, when the concentration of G is doubled keeping the concentration of H fixed, the rate is doubled. The overall order of the reaction is:
In a reaction, A + B→Product, rate is doubled when the concentration of B is doubled, and rate increases by a factor of 8 when the concentrations of both the reactants ( ) are doubled, rate law for the reaction can be written as:
For the reaction N2O5(g)
(g)
the value of rate of disappearance of N
2O5is given
as 6.25 m 10
–3 mol L–1 s–1. The rate
of formation of NO
2 and O2is given
respectively as:
A reaction involving two different reactants can never be:
Which of the following statement for order of the reaction is not correct?
When a bio chemical reaction is carried out in laboratory; outside the human body in the absence of enzyme, then the rate of reaction obtained is 10–6 times, than activation energy of reaction in the presence of enzyme is:
In the reaction: (aq) + 5Br
The rate of
appearance of bromine (Br
2) is related to the rate of disappearance
of bromide ions as
A follows the first-order reaction, (A)product Concentration of A, changes from 0.1 M to 0.025 M in 40 minutes. Find the rate of reaction of A when the concentration of A is 0.01 M.
If the pH is 4, the concentration of OH
If the pH is 3, the concentration of H
