B, If a force pushes the rock, it rolls down the hill because of the force of gravity. The potential energy is converted into kinetic energy until it reaches the bottom of the hill and stops. The water in a reservoir behind a hydropower dam is another example of potential energy.
Hexanoyl Chloride on treatment with excess
Ethyl Magnesium Bromide yields
tertiary Alcohol. In this reaction Hexanoyl chloride is first converted into
intermediate ketone (Octane-3-one), secondly the ketone formed is further reduced to <em>
tert.</em>
Alcohol (3-Ethyloctan-3-ol), The reaction along with mechanism is shown below,
Answer:

Given :
Concentration of product [A] = 0.371 M .
Rate constant , .
To Find :
The rate for the reaction .
Solution :
We know , for second order reaction , rate is given by :
Therefore , the rate for the second order reaction is 0.1 M/t .
Hence , this is the required solution .
Photosynthesis is process by which green plants and certain other organisms use the energy of light to convert carbon dioxide and water into the simple sugar glucose. In so doing, photosynthesis provides the basic energy source for virtually all organisms. An extremely important byproduct of photosynthesis is oxygen, on which most organisms depend.
