Answer:

Hope dat helps

Explanation:

All the data related to the potential energy diagram is shown in the attached image.

Reactants, intermediate, products, activation energy (Ea), and enthalpy change (ΔH).

Enthalpy change (ΔH) is the difference in energy between reactants and products.

ΔH = E of products - E of reactants.

Enthalpy of the reaction is defined as the difference in the potential energy of the products and the reactants. It is represented as

From the image, the points marked represents:

Point A represents the potential energy of the reactants.

Point B represents the intermediate state or transition state in a reaction.

Point C represents the potential energy of the products.

Arrow D represents the activation energy of the reaction.

Arrow E represents the enthalpy of the reaction.

Hence, arrow E represents the enthalpy of the reaction.

The emission spectrum of cesium contains two lines whose frequencies are (a)
Lady bird [3.3K]

The lines are violet and blue respectively.

<h3>What is the energy?</h3>

We know that the energy of the photon could be obtained by the use of the equation;

E = hf

E = energy

h = Plank's constant

f = frequency

For the first line;

E = 6.6 * 10^-34 Js * 3.45 x 10^14 Hz = 2.3 * 10^-19 J

Given that;

E = hc/λ

λ = hc/E

λ = 6.6 * 10^-34 * 3 * 10^8/2.3 * 10^-19

λ = 8.61 * 10^-7 m or 861 nm

The color is violet

For the second line;

E = 6.6 * 10^-34 Js * 6.53 xx 10^14 Hz

E = 4.3 * 10^-19 J

E = hc/λ

λ = hc/E

λ =  6.6 * 10^-34 * 3 * 10^8/4.3 * 10^-19

λ = 4.60 * 10^- 7 m or 460 nm

The color is blue
