There are 3 experiments which helps to under water evaporation system.

Both the temperature of the air surrounding the water and the rate of evaporation increased.
In the second experiment, we observed an increase in air flow around the water, and this time, the rate of evaporation increased as well.
In the third and final experiment, we observed an increase in the amount of light in the room, and this time, the rate of evaporation increased as well.
Because the kinetic energy of a substance can be measured by its temperature, increasing in the temperature or kinetic energy of the air around water will also increase the kinetic energy of the water, which will increase the rate of evaporation.
It's crucial to have good air flow since it drives water droplets in the air away from you, reducing the amount of humidity in the region. Because there will then be space for the evaporated air or space for the evaporated water to flow into the air, it will then be simpler for the water to really evaporate.
Water in the presence of sunlight is given extra energy, which increases evaporation.

Calculate the kinetic energy of a 150 g baseball moving at a speed of 40. m/s (89 mph).

LUCKY_DIMON [66]

Kinetic Energy= 0.5 times velocity squared times mass
So KE= 0.5times 150 times 40 squared

Consider the reaction: 2NO(g) + 2H2(g) → N2(g) + 2H2O(g) A suggested mechanism for this reaction follows: (1) NO(g) + NO(g) → N2

Dominik [7]

Hello. This question is incomplete. The full question is:

"Consider the following reaction. 2NO(g) + 2H2(g) → N2(g) + 2H2O(g)

A proposed reaction mechanism is: NO(g) + NO(g) N2O2(g) fast N2O2(g) + H2(g) → N2O(g) + H2O(g) slow N2O(g) + H2(g) → N2(g) + H2O(g) fast

What is the rate expression? A. rate = k[H2] [NO]2 B. rate = k[N2O2] [H2] C. rate = k[NO]2 [H2]2 D. rate = k[NO]2 [N2O2]2 [H2]"

Answer:

A. rate = k[H2] [NO]2

Explanation:

A reaction mechanism is a term used to describe a set of phases that make up a chemical reaction. In these phases a detailed sequence of each step is shown, composed of several complementary reactions, which occur during a chemical reaction.

These mechanisms are directly related to chemical kinetics and allow changes in reaction rates to be observed in advance.

Reaction rate, on the other hand, refers to the speed at which chemical reactions occur.

Based on this, we can observe through the reaction mechanism shown in the question above, that the action "k [H2] [NO] 2" would have no changes in the reaction rate.
