The lines are violet and blue respectively.
<h3>What is the energy?</h3>
We know that the energy of the photon could be obtained by the use of the equation;
E = hf
E = energy
h = Plank's constant
f = frequency
For the first line;
E = 6.6 * 10^-34 Js * 3.45 x 10^14 Hz = 2.3 * 10^-19 J
Given that;
E = hc/λ
λ = hc/E
λ = 6.6 * 10^-34 * 3 * 10^8/2.3 * 10^-19
λ = 8.61 * 10^-7 m or 861 nm
The color is violet
For the second line;
E = 6.6 * 10^-34 Js * 6.53 xx 10^14 Hz
E = 4.3 * 10^-19 J
E = hc/λ
λ = hc/E
λ = 6.6 * 10^-34 * 3 * 10^8/4.3 * 10^-19
λ = 4.60 * 10^- 7 m or 460 nm
The color is blue

Answer: Option (B) is the correct answer.
Explanation:
Whenever there is less concentration of solute particles in a solvent then it means less number of solute particles are available. As a result, there will occur less number of collisions between the solvent and solute particles.
It means that there will be a decrease in rate of reaction.
But if there is more concentration of solute particles then it shows more number of solute particles are available for reaction. As a result, more number of collisions will take place between the particles of solute and solvent.
Hence, then there will occur an increase in rate of reaction.
Thus, we can conclude that a lower concentration of dissolved particles decrease the reaction rate because when there are less dissolved particles, less collisions take place.
An oxidation-reduction (redox) reaction is a type of chemical reaction that involves a transfer of electrons between two species. An oxidation-reduction reaction is any chemical reaction in which the oxidation number of a molecule, atom, or ion changes by gaining or losing an electron.
