Answer:
The answer to your question is A and B
Explanation:
Chemical reactions can be classified by the energy that they need to proceed or the energy they release.
Endothermic reactions are reactions that require energy to proceed most of the time this energy is in the form of heat.
Exothermic reactions are reactions that release energy to proceed, this energy could be in the form of heat or light.

Wavelength of the radio wave can only be identified if theirs an image. Radio wave doesn't have a fixed wavelength unless we are talking about the frequency than its 10^3
Answer: ![Rate=k[A][B]](https://tex.z-dn.net/?f=Rate%3Dk%5BA%5D%5BB%5D)
Explanation:
Rate law says that rate of a reaction is directly proportional to the concentration of the reactants each raised to a stoichiometric coefficient determined experimentally called as order.
Order of the reaction is defined as the sum of the concentration of terms on which the rate of the reaction actually depends. It is the sum of the exponents of the molar concentration in the rate law expression.
For reactions which takes place in multiple steps are complex reactions and the order is given by the slowest step which is the rate limiting step.
For the given reaction, the rate limiting step is
![A+B\rightarrow D](https://tex.z-dn.net/?f=A%2BB%5Crightarrow%20D)
Rate law will be , ![Rate=k[A][B]](https://tex.z-dn.net/?f=Rate%3Dk%5BA%5D%5BB%5D)
