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
What else can I help you with?
The decomposition reaction of ammonia gas on platinum surface has a rate constant k equals 2.510-4 mol l-1s-1 what is the order of the reaction?
The rate constant is not indicative of the order of the reaction. To determine the order of the reaction, experimental data (such as concentration vs. rate data) is needed. The order of the reaction can be found by examining how changes in reactant concentrations affect the rate of the reaction.
What is the overall reaction order for this rate law rate equals kA2BC?
The overall reaction order for k[A]^2[B][C] would be 4 Because [A] has a rate order of 2 [B] has a rate order of 1 [C] has a rate order of 1 And when you add them together... 2 + 1 + 1 You obtain four
What 4 factors increase a reaction rate?
Increase in temperature: Higher temperature provides molecules with more kinetic energy, increasing the frequency of collisions between reactant particles. Higher concentration of reactants: More reactant molecules present in a given volume increases the likelihood of collision. Catalysts: Catalysts provide an alternative reaction pathway with lower activation energy, speeding up the reaction. Increased surface area: Finely dividing or dispersing reactants exposes more surface area, facilitating more collisions and increasing the reaction rate.
What would happen to the rate of a reaction with rate law rate kno2h2 if the no were doubled?
the rate would be four times larger. apex
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.

What are 4 things that affect the rate of a reaction?
1. The concentration of the substances. 2. The temperature. 3. The surface area of the particles. 4.The presence of a catalyst.
What factor does affect the most rate of reaction?
The concentration of reactants is the factor that most significantly affects the rate of reaction. Increasing the concentration of reactants typically leads to more frequent and successful collisions between particles, resulting in a higher reaction rate.
What are 4 things can increase reaction rate?
Increasing temperature, increasing concentration of reactants, using a catalyst, and increasing the surface area of the reactants can all increase reaction rate by providing more energy for collisions between reactant molecules.
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 statements about activation energy is correct?
Activation energy is the minimum amount of energy required for a chemical reaction to occur. An increase in activation energy leads to a decrease in reaction rate. Catalysts lower the activation energy required for a reaction to proceed, increasing the reaction rate. Activation energy does not affect the overall energy change of a reaction, only the speed at which it occurs.
What would happen to the rate of a reaction with rate law rate kno2h3 if the concentration of no were doubled?
If the concentration of NO was doubled in the rate law rate = k[NO]2[H3], the rate of the reaction would increase by a factor of 4. This is because the rate of a reaction typically increases with an increase in the concentration of reactants, raised to a power dictated by their respective coefficients in the rate law equation.
What is the overall reaction order for this rate law rate equals kA2BC?
The overall reaction order for k[A]^2[B][C] would be 4 Because [A] has a rate order of 2 [B] has a rate order of 1 [C] has a rate order of 1 And when you add them together... 2 + 1 + 1 You obtain four
What 4 things affect a plant?
depends
What would happen to the rate of a reaction with rate law kNO2H2 if the concentration of NO were doubled?
The rate would be four times larger
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 the four factors that affect the rate of a chemical reaction?
The four factors that affect the rate of a chemical reaction are the concentration of reactants, temperature, presence of a catalyst, and surface area of reactants (for reactions involving solids or liquids). These factors influence how frequently and effectively particles collide to form products.
