What is the energy of light with frequency equal to 4.3 x 10^10 s^-1?

Explanation:

Given that,

The frequency of light,

We need to find the energy of light. The formula for the energy is given by :

Where h is Planck's constant

Putting all the values of h and f, we get :

So, the energy of light is .

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.
