What is the molecularity of the following elementary reaction?
1 answer:
Answer : The correct option is, (B) bimolecular
Explanation :
Molecularity : It is defined as the total number of reactant molecules taking part in the balanced equation of a reaction. It is a theoretical concept.
The given balanced chemical reaction is,
The number of reactants molecules taking part in the balanced equation of a reaction are, and
.
In this reaction, 1 molecules reacts with the 1
molecule.
Total number of reactant molecule = 1 + 1 = 2
The molecularity of the reaction is 2 that means, the elementary reaction is bimolecular.
Hence, the correct option is, (B) bimolecular

Answer:
The speed of an electron is 0.01908 m/s.
Explanation:
De-Broglie wavelength is given by:
where, = wavelength of a particle
h = Planck's constant =
m = mass of particle
v = velocity of the particle
Velocity of an electron = v
Mass of an electron =
Wavelength of electron is twice the displacement in seconds which is velocity of an electron.
Then.wavelength of an electron =
v = 0.01908 m/s
The speed of an electron is 0.01908 m/s.
