What are things that decrease a reaction rate?
Some factors are: low temperature, low pressure, low concentration of reactants, no stirring, coarse particles, etc.
What 4 things affect how fast a substance dissolve?
The particle size,temperature and agitation affect the rate at which a substance will disolve in a solution.
What would happen to the rate of a reaction with rate law rate kNO2H2 if the concentration of NO were double?
The rate would quadruple (increase by a factor of 4). This is because the rate depends on the SQUARE of the concentration of NO.
What are 4 factors that affect a wave's rate of erosion?
Erosion,weathuring,andclimate
Can rate of reaction be negative?
As far as I know, No. A negative order means a higher concentration of the reactant having a lower reaction rate. For example: concentration of A reaction rate ---- 4 M .1 M/s 1 M .4 M/s ---- rate1/rate2=k(A1)n/k(A2)n k canceled (.1M/s)/(.4M/s)=(4M/1M)n 1/4=4n n=-1 but the reaction rate is usually proportional to the concentration of the reactant, which means reactants with a higher concentration have a greater reaction rate, in a few case, increase the concentration of reactant have little effect for the reaction rate. So, the order of the reaction is usually positive in a few case, it's close to 0.

What 4 factors increase a reaction rate?
4 factors that affect reaction rate are Temperature, Stirring, Concentration, and Pressure (only for gases).
What factor does affect the most rate of reaction?
Factors affecting the rate of reaction 1. Temperature 2. Catalyst 3. Concentrations of the reactants 4. Nature of the reactants 5. Surface area of the reactants

What 4 things affect how fast a substance dissolve?
The particle size,temperature and agitation affect the rate at which a substance will disolve in a solution.
What factors change the rate of chemical reaction?
Adding a catalyst to the process will make the chemical reaction go faster. Also, the temperation, concentration, state of matter and pressure will affect the rate of the chemical reaction.
What are the four factors that affect the rate of a chemical reaction?
Whether a catalyst is present or not, Concentrations of reactants, Temperature, Pressure (but this is least likely to affect rate)
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
4 factors that affect the growth rate of a population?
Birth rate: The number of individuals being born into the population. Death rate: The number of individuals dying in the population. Immigration: The movement of individuals into the population. Emigration: The movement of individuals out of the population.
What would happen to the rate of a reaction with rate law rate kNO2H2 if the concentration of NO were double?
The rate would quadruple (increase by a factor of 4). This is because the rate depends on the SQUARE of the concentration of NO.
What 4 things affect a plant?
depends
4 factors that affect blood pressure?
There are four factors that affect the blood pressure. The things that can affect blood pressure are stress, genetics, a high salt intake, and exercise.
Effect of ionic strength on rate of reaction?
The rate of reaction basically depends on the product of charges of ions present in a solution. Since the compounds dissociate in a solution and forms cations and anions, so their product matters a lot. If the product of charges is positive ( i.e. one ion is +1 and other is +4 = +4 ), then the rate of reaction will increase automatically, higher the product faster will be the rate. Similarly, if the product of ions present in a solution is negative ( i.e. one ion is +1 and other is -3 = -3) then the rate of reaction will decrease. For those reactions in which neutral species are present and for which the product of charges will be zero, there will be no effect on the rate of reaction.
