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 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 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.
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 are 5 ways to control a chemical reaction?
Adjusting the concentration of reactants: By changing the amount of reactants present in a chemical reaction, you can control the rate at which the reaction occurs. Modifying the temperature: Increasing or decreasing the temperature can alter the kinetic energy of molecules, affecting the reaction rate. Using a catalyst: Catalysts are substances that can speed up a reaction without being consumed, providing an alternative pathway for the reaction to proceed. Changing the pressure: For reactions involving gases, adjusting the pressure can influence the reaction equilibrium and rate. Stirring or mixing: Enhancing the mixing of reactants can increase the frequency of collisions between molecules, promoting the reaction process.

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.
4 What happens when you increase the surface area of reactants in a reaction?
In general increasing surface area will increase the rate of a reaction by allowing more sites for the reaction to take place. However it is hard to answer this question without knowing the specific material in question.

the rate would be four times larger. apex
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 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 other two ways of increasing rates of reaction?
There are 4 ways to speed up rate of reactionTemperature - if you increase this then ther will be more molecules with sufficient energy to reach 'over' the activation energy barrierConcentration - there are more molecules, so more collisionsCatalyst (or enzyme in bio-organic reactions) - this is a substance that speeds up the rate of reaction as it lowers the activation energy reaction 'barrier', meaning more collisions will be succesfulSurface Area - if one of the reactants is a solid then breaking it up it into smaller pieces will increase surface area at which more molecules can collide to react.It's all based on the collision theory.
By what factor will the rate of the reaction change if the pH changes from 6.50 to 2.00?
The rate of a reaction can change significantly with pH. In general, for every unit change in pH, the reaction rate can change by a factor of 10. So, if the pH changes from 6.5 to 2, the rate of the reaction could potentially increase by a factor of 10^4 = 10,000.
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 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 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
