Why does radiation decrease over time?
Aleksandr-060686 [28]

Radiation decrease over time due to the concentration of radioactive atoms and the concentration decreases as radioactive particles are emitted (Option D).

<h3>What is radiation?</h3>

Radiation refers to the transmission of energy by means of subatomic particles that travel as waves.

Radioactive isotopes are also known as radioisotopes, which have unstable combinations of subatomic particles (i.e., neutrons or protons) in their atomic nuclei, and thus may emit alpha particles, gamma rays or beta particles.

Radioactive isotopes such as C14 lost (emit) energy per unit of time, which is known as radiation or radioactive decay.

In conclusion, radiation decrease over time due to the concentration of radioactive atoms and the concentration decreases as radioactive particles are emitted (Option D).

If you start with 0.05 M O3 and 0.01 M NO and the reaction reaches completion in 16 seconds, what is the initial rate of this re
makvit [3.9K]

Since we are basing the rate with respect to O3, therefore the rate would simply be the concentration divided by the total reaction time. That is:

rate of reaction = 0.05 M / 16 seconds

rate of reaction = 3.125 x 10^-3 M / second

or

<span>rate of reaction = 0.003125 M / second</span>
