The frequency of the ray with a wavelength of 3.10 × 10¹⁴ is 9.671 × 10⁻⁷.I attached the working and the answer to the question below. I hope I was able to help.
Please note that C = speed of light, ν = frequency and λ= wavelength.
Answer: C) It increases with a decrease in the concentration of . D) It decreases with increase in the concentration of .
Explanation: According to Le Chatelier's principle, if an equilibrium reaction is disturbed, the reaction would try to undo the change imposed.
Thus if the concentration of the products in increased, the reaction would shift in a direction where the concentration of products is decreasing i.e in backward direction.
If the concentration of the products in decreased, the reaction would shift in a direction where the concentration of products is increasing i.e in forward direction.
When the concentration of either of the products, i.e or is increased, the reaction will shift in backward direction and the rate of forward direction decreases.
It forms magnesium nitride
