A higher concentration of a catalyst will speed up the reaction rate.
the concentration of reactants generally increases the rate of reaction because more of the reacting molecules or ions are present to form the reaction products.
1. Increasing the concentration of one or more reactants will often increase the rate of reaction. This occurs because a higher concentration of a reactant will lead to more collisions of that reactant in a specific time period.
2. Physical state of the reactants and surface area.
a) The higher the concentration, the higher the boiling point. You can think of this effect as dissolved solute crowding out solvent molecules at the surface, where boiling occurs. The higher the concentration of solute, the more difficult it is for solvent molecules to escape into the gas phase.
b ) The more concentrated a solution, the more the freezing point of water will be depressed. The solute particles basically interfere with the ability of the water molecules to freeze because they get in the way and make it more difficult for the water to hydrogen bond
Answer / explanation:
How does concentration affect boiling point of a solvent?
The amount by which the boiling point is raised is directly dependent on the concentration of the solute.
The higher the concentration of a solute, the more it is said to be difficult for the solvent molecules to escape into the gas phase.
However, when a non volatile amount of substance is dissolved in a given solvent, the boiling point of the given solvent increases.
The higher the concentration, the more higher the boiling point of a solvent.
It requires a higher temperature for enough solvent molecules to escape , this the boiling point is raised elevatedly
Reaction rates are defined as the change in the concentration of a reactant or product per unit time. During a reaction, the concentration of a reactant decreases exponentially with time while that of a product increases exponentially with time.
Some of the factors affecting reaction rates are:Nature of the reactantsConcentration of the reactants or pressure of gasesTemperature Presence of a catalystSunlightThe rate of a reaction is directly proportional to the concentration of the reactants. The higher the concentration of a reaction, the faster it proceeds.

It's like rugby 7s and 15s
Rugby 7s has only 7 players from each each team playing, so the game is mostly centered about dodging with the ball and there is a lesser chance of getting tackled. Rugby 15s on the other hand, has the same field, but more people in the field, instead of 7, it's 15 from each side. Now there is a high possibility of getting tackled if you have the ball.Same principle with reactions but with molecules colliding instead.Tackling (collision)
