1 answer:
Explanation:
An alpha particles is basically a helium nucleus and it contains 2 protons and 2 neutrons.
Symbol of an alpha particle is .
A beta particle is a particle with a negatively charged electron. Symbol of a beta particle is .
According to the given question, the decay series chart along with reaction equation are as follows.
(a) Lead-214 changes to bismuth-214.
(b) Bismuth-214 changes to polonium-214.
(c) Polonium-214 changes to lead-210.
Therefore, we can conclude that proper order of nuclear particle emission is beta, beta, alpha.

<u>Answer:</u> The of the reaction is
<u>Explanation:</u>
For the given half reactions:
Oxidation half reaction:
Reduction half reaction:
Net reaction:
Oxidation reaction occurs at anode and reduction reaction occurs at cathode.
To calculate the of the reaction, we use the equation:
Putting values in above equation, we get:
To calculate equilibrium constant, we use the relation between Gibbs free energy, which is:
and,
Equating these two equations, we get:
where,
n = number of electrons transferred = 2
F = Faraday's constant = 96500 C
= standard electrode potential of the cell = 0.48 V
R = Gas constant = 8.314 J/K.mol
T = temperature of the reaction =
= equilibrium constant of the reaction = ?
Putting values in above equation, we get:
Hence, the of the reaction is
