The drawing shows a chemical reaction between hydroxide and bromomethane to produce methanol and bromide ion. the middle drawing
is the activated complex. the reaction is exothermic. which species has the highest energy?
1 answer:
Considering the attached diagram; The species that has the highest energy is structure B. This is because it is in the transition state, which has the highest energy. Looking at it there is no stable bonding for the atoms involved; it must change to either structure A or C to exist. A catalyst will lower this added energy, the activation energy, and allow the reaction to progress at a higher rate.

Solution :
Let, intensity at distance 3 m from the acoustic source is .
We need to find the distance d where the intensity is .
Now, we know intensity is inversely proportional to square of distance between the source.
Therefore, intensity will be halved at a distance of .
