The reaction is first order with respect to the reactant. In a first-order reaction, the rate is directly proportional to the concentration of the reactant. Doubling the concentration of a reactant will result in a doubling of the reaction rate.
If the order of a reactant is zero, its concentration will not affect the rate of the reaction. This means that changes in the concentration of the reactant will not change the rate at which the reaction proceeds. The rate of the reaction will only be influenced by the factors affecting the overall rate law of the reaction.
It reduces it. This is because when reactions occur the atoms 'bump into' each other. The less atoms per space (decreased concentration) the less bumping in a given period takes place, therefore creating a slower reaction.
Increasing the concentration of reactants generally increases the rate of a reaction because there are more reactant particles available to collide and form products. This leads to more frequent and successful collisions, ultimately speeding up the reaction time.
Pretty simple, really. For any one "A" molecule, if there are twice as many of the other "B" molecule present then the odds of it colliding with one of them are twice as high. The same equations for effective collisions hold, so doubling the concentration doubles the reaction rate.

Decreasing the concentration of a reactant will typically decrease the rate of a chemical reaction, as there are fewer reactant molecules available to collide and form products. This is in line with the rate law, which often shows a direct relationship between reactant concentration and reaction rate.

To determine the order of a reaction from a table, you can look at how the rate of the reaction changes with the concentration of reactants. If doubling the concentration of a reactant doubles the rate, the reaction is first order with respect to that reactant. If doubling the concentration quadruples the rate, the reaction is second order. And if doubling the concentration increases the rate by a factor of eight, the reaction is third order.
The rate law expresses the relationship between the rate of a chemical reaction and the concentrations of the reactants. It is typically formulated as Rate = k[A]^m[B]^n, where k is the rate constant, [A] and [B] are the concentrations of the reactants, and m and n are the reaction orders which indicate how the rate changes with concentration. If the concentration of a reactant increases, the rate of reaction will typically increase as well, depending on its exponent in the rate law, reflecting the dependency of reaction kinetics on reactant concentrations. Thus, the rate law quantitatively describes how variations in concentration influence the speed of the reaction.
The rate of a chemical reaction that is most dependent on the concentration of the reactants is known as a first-order reaction. In a first-order reaction, the rate of the reaction is directly proportional to the concentration of one reactant. Therefore, changes in the concentration of the reactant directly impact the rate at which the reaction proceeds.
Reactant concentration refers to the amount of a reactant present in a specific volume of a solution or mixture. It is typically measured in moles per liter (M) or molarity (M) and is a key factor that influences the rate of a chemical reaction.
Decreasing the reactant concentration will slow the rate of the reaction. If you use the idea of adding oxygen and hydrogen to make water and decease the amount of one, you will produce less water. It doesn't matter which reactant is less as there are just are not enough to go around.
A first-order reaction will never be completed because the reaction rate depends only on the concentration of one reactant. As the reaction progresses and the reactant is consumed, the concentration of the reactant decreases, causing the reaction rate to also decrease. This gradual decrease in reaction rate means that the reaction will continue indefinitely, given enough time.
It leads to more frequent collisions, which increase reaction rate.
Changes in concentration affect the rate of the reaction as defined by the rate law equation. Increasing the concentration of reactants typically leads to an increase in the reaction rate since there are more reactant particles available to collide and form products. The rate law equation quantifies this relationship between concentration and reaction rate through the reaction order with respect to each reactant.
