Answer: 
Hz
Explanation: Recall the formula for the speed of light is
where 
is the speed of light,
is the wavelength, and 
is the frequency. Assuming this takes place in a vacuum, 
m/s. Now we can solve for frequency
(rounding to 3 sig figs)
Thus, the frequencyis Hz.
It would be false adding a solute to a solvent

Answer:
d) The fraction of collision with total kinetic energy larger than activation energy increases.
Explanation:
Hello,
In this case, kinetic models explain how the rate of a chemical reaction is affected by several factors. In such a way, specifically for temperature, when it increases, the average velocity of the particles is also increased, for that reason, the collision frequency increases since the molecules are more likely to collide as they move faster and encounter to each other.
Nonetheless, it is the minor reason because the main reason is that the effective collisions increase when the temperature is increased, and they are related with the fraction of collision with total kinetic energy that turns out larger than the activation energy, therefore, answer is d).
Best regards.
