The path way A-B-D involves a catalyst and is slower than A-C-D

Explanation:

The diagram above shows the path taken by a chemical reaction when a catalyst is used and also when no catalyst is used.

The catalyzed path is indicated with the broken lines i.e the path A-B-C while the uncatalyzed path is indicated with the small thick line i.e the path A-C-D.

The catalyzed path has a higher peak (activation complex) than the uncatalyzed path. This implies that the activation energy of the catalyzed path is higher than that of the uncatalyzed path. Therefore more energy will be required to overcome the barrier (i.e the activation energy) in the catalyzed path and hence the reaction will be slower when compared to the uncatalyzed path which have a lower energy barrier (i.e the activation energy) and needs little energy to overcome the energy barrier (i.e the activation energy).

Note: reaction with high activation energy tends to be slower when compared with those with low activation energy.

the tides are influenced by both the moon and the sun, it's easy to see that when the sun lines up with the moon and the earth, as during a new moon or full moon, the tidal effect is increased. these are known as spring tides, named not for the season, but for the fact that the water "springs" higher than normal. on the other hand, if the sun and the moon are 90 degrees apart in relation to an observer on earth as during the first quarter moon or third quarter moon, then high tides are not as high as they normally would be. this is because despite its greater distance, the sun's mass allows it to exert enough gravitational force on the oceans that it can negate some of the effects of the moon's pull. this phenomenon of lower high tides is called a neap tide. if you need more information on this topic visit moonconnection.com.
