Introduction: Reaction rates are also influenced by surface area and concentration. The surface area of a solid is a measure of
how much of the solid is exposed to other substances. The concentration of a substance is a measure of how many molecules of that substance are present in a given volume. Question: How do surface area and concentration affect reaction rates
Surface area has to do with the number of solid particles that are exposed at a given time and is capable of colliding with other reactant particles. When more surface area is exposed for reaction, then it means that more particles are likely to collide with each other leading to faster chemical reaction rates. When few particles are exposed for reaction (low surface area) then less collisions occur and the rate of reaction is decreased.
Similarly, concentration refers to the amount of substance present. The greater the amount of substance present, the greater the likelihood of collision between particles and the greater the rate of reaction and vice versa.
The answer is 22 degrees. Law of conservation of energy stipulates that energy cannot be created or destroyed but can be transferred and also transformed from one form to another. The movement of the container, mechanical energy, was transferred to the water, as heat energy, and therefore raised the water temperatures slightly.
