Question

What are factors that DO NOT affect the speed of the reaction? Does the mass of a solid solute directly influence the rate of reaction?

Answer 1

Well its a bit tricky question. The speed of reaction (or rate of reaction) depends on type of mechanism it follows. In SN2 reaction mechanism rate of reaction depends on both reactant and concentration of nucleophile, whereas in SN1 reaction rate depends on only reactnat (substrate). Generally almost every parameter has its own influence on speed of reaction. Examples like solvent polarity, temperature, pressure, concentration and catalyst.

But the number of protons and neutrons present in the molecule do not effect the speed of reaction. Electrons are responsible as their lost gives cation and gaining gives anion, charged particles have an effect on rate of reaction, more the charge seperation, the more they attract each other and fruitful collision takesplace for better spped of reaction.

Smaller reactant particles with less mass increase the chances for collisions, which increases the reaction rate. While bigger reactant particles with higher mass decrease the chances for collisions, which decreases the reaction rate. We know that reaction depends on collisions. The more surface area on which collisions can occur, the faster the reaction.
