First, assume the order of the given reaction is n, then the rate of reaction i.e.
where, dx is change in concentration of A in small time interval dt and k is rate constant.
According to units of rate constant, the reaction is of second order.
(second order formula)
Put the values,
t= 587.9 s
Hence, time taken is 587.9 s
Answer:
The wavelength of the line in the absorption line spectrum of hydrogen caused by transition is 657.1 nm.
Explanation:
Energy of the electron in a hydrogen atom in nth shell:
Energy of an electron in n = 2:
Energy of an electron in n = 3:
Energy difference in between both the shells:
:
=
The wavelength of the line in the absorption line spectrum of hydrogen caused by transition is 657.1 nm.
