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.

Does the mass of a solid reactant affect the reaction rate?
yes it does
How does the concentration of reactant affect the rate of a reaction?
Increasing the concentration increases the molecules' collision frequency.
What are 4 things that can affect the rate of a reaction?
1. Temperature: Depending on the temperature of the reactants, the reaction rate will differ. The higher the temperature (or the hotter the reactant is), the quicker the reaction will occur. The cooler the reactant is, the longer it will take for a reaction to take place. The heat causes the particles to move quickly, and due to the Collision Theory, which states that in order for a reaction to occur, molecules must collide, the particles will be more likely to bump into each other, and so the reaction will occur faster.2. Concentration: The higher the concentration of a reactant, the quicker the reaction will occur. This means that there are more particles of that particular substance, meaning it will collide more frequently into the particles of the other reactant. This increases the reactant rate because the more concentrated a reactant is, it means that the less space there is between the two reactants.3. Surface Area: Basically, the more particles that are exposed during the experiment, the faster the reaction will occur. The more the particles are exposed, the faster it is for the other reactant to collide into the particles, meaning the reaction rate will increase.4. Catalysts: Catalysts are substances that increase the rate of reaction by speeding up the reaction without being used up in the reaction. It does not affect the reactants in any other way than making them collide into each other more frequently, and it doesn't affect the product (or products) produced
How will decreasing the reactant concentration affect the rate of reaction?

How does decreasing reactant concentration affect the rate of 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.
How does an increase in reactant concentration affect the rate of reaction?
It leads to more frequent collisions, which increase reaction rate.
How will decreasing the reactant concentration affect the reaction?
It depends on the order of the reaction. If it is zero order, decreasing the reactant concentration will have NO effect on the rate. If it is 1st or 2nd order (or more), then decreasing the concentration will DECREASE the reaction rate.
If the order of a chemical reaction with respect to one of its reactants is zero how does that reactant's concentration affect the rate of the chemical reaction?
It doesn't - the reaction rate will not change regardless of how much of that reactant is added. That's the definition of zero-order.
Does the amount of reactant affect the amounts of product?
The more reactant, the faster the reaction The less reactant, the slower the reaction hope that clears it up for you
How does concentraition affect the rate of a chemical reaction?
Usually, increasing concentration of reactants increases the rate of reaction, but increasing concentrations of products reduces the rate of reaction. However, if one reactant is already present in large stoichiometric excess over another, increasing the concentration of that reactant may not increase the rate of reaction at all, and if the free energy of reaction is large enough in magnitude, increasing the concentration of products may not reduce the rate of reaction at all.
Does the mass of a solid reactant affect the reaction rate?
yes it does
How factors affect rates of physical change?
-Reactant Concentration • The greater the concentration of reactants (the more particles per unit volume), the greater will be the number of effective collisions per unit time, and therefore, the reaction rate will generally increase. • For zero order reactions, however, the reaction rate is not dependent on the concentration of reactants. Increasing the reactant concentration will have no effect on the rate. -Temperature • The reaction rate will increase as the temperature of the system increases. As the temperature increases, the reactant molecules have more energy. They thus find it easier to climb the energy barrier to the reaction (the activation energy). -Solvent • The reaction rate will increase as the temperature of the system increases. As the temperature increases, the reactant molecules have more energy. They thus find it easier to climb the energy barrier to the reaction (the activation energy).
How can affect of heat on a reaction be determined?
heat is treated as a reactant or a product
A factor that affects the rate of reaction?
There are several factors that affect the rate of reaction: -The surface area available. -Temperature -Availability of catalyst. -Concentration, if a/the reactant(s) is/are solutions. -Pressure, if a/the reactants(s) is/are gases. -Reactivity of reactants. -Activation energy of the reaction.
How does the concentration of reactant affect the rate of a reaction?
Increasing the concentration increases the molecules' collision frequency.
