Answer:
wavelength = 0.56 × 10⁻² m
Explanation:
Given data:
Frequency of radiation = 5.4 × 10¹⁰ Hz
Wavelength = ?
Solution:
Formula:
speed of light = wavelength × frequency
wavelength = speed of light / frequency
wavelength = 3 × 10⁸ m/s / 5.4 × 10¹⁰ Hz ( Hz= 1/s)
wavelength = 0.56 × 10⁻² m
First, assume the order of the given reaction is n, then the rate of reaction i.e. ![\frac{dx}{dt}=k\times[A]^{n}](https://tex.z-dn.net/?f=%5Cfrac%7Bdx%7D%7Bdt%7D%3Dk%5Ctimes%5BA%5D%5E%7Bn%7D)
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
