What is collision theory
The collision theory is when atoms, molecules or ions bash
together or collide together.
Collision theory states that the rate of a reaction may be
increased by : increasing pressure; raising the amount of heat
energy; raising the concentration of the reactant and by
introducing a catalyst.
What speeds up a reaction
more catalysts, surface area, concentration, or temperature
It is true that cold usually speeds up reaction rates
No, low temperatures usually slow down reaction rates.
Is it true that a low concentration of a chemical slows reaction rate
true!!! concentration affects reaction rate, the higher the
concentration the faster the reaction.
How does Erosion of Shoreline Affect Water quality
Does every collision between reacting particles leads to products
No, only effective collisions (having specific orientations)
leads to products.
Write a c program to find Volume and surface area of cube
Write a c program to compute the surface area and volume of a
cube
Is nitrogen oxide an acid
Nitrogen oxide is not considered an acid because it does not
dissociate in water.
Is set a action or linking verb
Set is an action verb, as in I set the glasses on the table, or
I set the table. It will never be a linking verb.
What are different factors that affect the rates of chemical reactions
Some different factors that affect the rates of chemical
reactions include whether or not a catalyst is present, the
concentration of the reactants, temperature of the reactants, &
pressure in the case of gas phase reactions.
The addition of a increases the rate of reaction by providing an alternative pathway with a lower activation energy
The addition of a catalyst increases the rate of reaction by
providing an alternative pathway with a lower activation
energy.
