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.
What can speed up an enzyme reaction?
An increase in temperature can increase the enzymatic reactions if it is not too hot and also if the pH is within the idea range it can speed up the reaction. The pH level is usually around 7 for most enzymes.
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 is the relationship between substrate concentration and enzyme activity?
At low substrate concentrations, the rate of enzyme activity is proportional to substrate concentration. The rate eventually reaches a maximum at high substrate concentrations as the active sites become saturated.
When a reaction is at the equilibrium's will increasing pressure favor the reaction that produces more gas?
Not usually. This could only happen if the gas produced were so far from ideal that its production reduces the pressure of the total mixture of reactants and products, a very unlikely occurrence.

What can increase the chance of a reaction when two molecules collide?
An increase in the temperature usually increases the rate of reaction by increasing the number of collisions.
Why does increasing the pressure of the gas usually increase reaction rate?

Why does increasing concentration usually increase reaction rate?
Lncreasing the number of particles in a given volume, means they are more concentrated. Since there are more particles in a given volume it means that they will collide more often with the reacting particles. 'More often' means an increasing rate of reaction.

If you were to raise the temperature of the solvent could the concentration levels of the solution increase?
Solubility of any solvent is usually temperature dependent and yes, the solubility of most salts increase when the temperature is increased. However the solubility of some salts also decreases with increasing temperature.
Increased temperature usually leads to an increase in reaction rate because collisions are?
The increase in reaction rate is due to an increase in the number of collisions. This is because an increase of temperature causes an increase in molecular motion.
What makes chemical reaction to go faster?
cofee or nos or an energy drink would speed up a chemical reaction..
Which methods will usually cause a reaction to speed up?
Combining the reactants at a lower temperature. Reducing the concentration of reactants. Grinding one of the reactants into a powder. Removing the catalyst.
List five ways you could increase the rate of a chemical reaction?
1) Add a catalyst 2) Add heat 3) Stir 4) Mix 5) Surface area of the reactant
What is the process of Increasing Term Life Insurance?
Increasing term life insurance will increase in its value over time usually at a rate proportional to inflation. The premiums will increase over time, as well as the overall value of the policy.
