The fourth postulate of kinetic theory states that collisions between particles occur quickly such that most of the time particles are in motion and not colliding Predict the effect of increasing the?
Increasing the concentration of the reactants will increase the rate of collisions, but will not change the fact that most of the time particles are in motion and not colliding.
Why will increasing the substrate concentration not decrease the effect of a non competitive inhibitor?
Because you will still have the same number of enzymes inhibited. For example, you have 20 enzymes and 10 non-competitive inhibitors. Regardless of substrate concentration, at any one time, there will only be 10 enzymes available to accept a substrate. Increasing the substrate concentration does not affect this.
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.
How does increasing the concentration affect the rate of a chemial or physical change?

How are the concentration of the reactants and reaction rate related?
rate laws a+the higher the concentration = more particles = higher chance of a collision happening = higher/faster reaction rate

Increasing the concentration of the reactants will increase the rate of collisions, but will not change the fact that most of the time particles are in motion and not colliding.
What effect does the concentration on reactants have on the rate of a reaction?
increasing the concentration increases the rate of the reaction
What effect does the concentration of reactants have on the rate of reaction?
increasing the concentration increases the rate of the reaction
What effect of concentration of reactants have on the rate of a reaction?
increasing the concentration increases the rate of the reaction
How does changing the substrate concentration exhibit the same effect as changing the enzyme concentration?
For the enzyme to work, its particles must collide with the particles of the substrate. The more particles there are per unit volume, the more frequent the collisions will be. Thus changing the concentration of either chemical will have the same effect.
What is the effect varying the concentration on the rate of reaction time?
Increasing the concentration of the reactants the rate of reaction increase.
What would make the greenhouse effect stronger?
increasing the CO2 concentration in the atmosphere
Which would make the greenhouse effect stronger?
Increasing the CO2 concentration in the atmosphere
What would speed up a reaction?
increasing the concentration of reactants
What is the effect of increasing the concentration of enzymes in a reaction?
If the reaction speed has not already peaked, then it will increase
What effect does the concentrate of reactants have on the rate of a reaction?
increasing the concentration increases the rate of the reaction
Why addition of water to vinegar does not effect the determination of its concentration in titration?
Yes, it DOES effect the concentration (mol per litre). This is because the volume (of solution, litres) has changed, when diluting, but not the total quantity (just moles of 'reacting' vinegar in the titration).
