Question

The surface are is affected by​

Answer 1

Complete step by step answer:To understand this we should consider first the collision theory.Which states that chemical reactions can only take place when the reacting particles collide with each other. The collisions must have sufficient energy.The role of a chemical reaction is determined by the frequency of successful collisions.Frequency means: Number of successful collisions per second.When particles in the solution react they can only react with particles on the surface of that molecule or compound.The particles that are not on the surface do not have contact with solution and hence they don’t react.But when that molecule is divided into further particles the surface area increases, that is there are more particles on the surface to react.Now the surface area has increased. Because we have more collisions per second, the rate increases when we increase the surface area.When you grind a solid into fine powder now the same number of moles of reactant exist in a greater surface area from.
