Write a paragraph explaining the effect of surface area on the rate of reaction.
nexus9112 [7]
(For a bit of context I will use the reaction between HCl and Mg as an example)

The larger the surface area of the magnesium metal, the more particles are exposed to collide with the aqueous HCl particles to cause the reaction to occur. This increases the frequency per second of collisions, speeding up the rate of reaction.

The effect of a catalyst is to reduce the minimum collision energy which allows the reaction to happen. This does not increase the number of collisions per second, but increases the percentage of successful collisions, which consequently causes the rate of reaction to increase .

I have drawn diagrams showing the effect of surface area, but there isn't really a meaningful diagram that I know of to show the impact of a catalyst (at least not at GCSE level).

As much as 25 percent of the fruits and vegetables grown in Chinese agricultural regions rot before they can be transported the
gulaghasi [49]

C. Developing effective methods of food preservation

Explanation:

The development of effective methods of food preservation is a much more smaller and manageable problem that contributes to the complex problem.

The percentage of food rotting is not as a result of lack of an effective preservation technique as highlighted in the passage. It is due to the long distances of agricultural area from where the farms are located.

  • To cut the loss, efficient and rapid transportation techniques needs to be put in place to carry the fruits and vegetables to the area where they are needed.
  • This is the most complex problem that if solved can peg back food rot.
  • Additional measures should be put in place to preserve the food.

Other options does not address the subject matter
