Delimiter between question and answer:

Tips:

  • No column headers.
  • Each line maps to a question.
  • If the delimiter is used in a question, the question should be surrounded by double quotes: "My, question","My, answer"
  • The first answer in the multiple choice question must be the correct answer.

What effect does an increase in concentration have on rate of reaction?
Particles closer together, more collisions mean more successful collisions and increased rate
Explain how the Maxwell Botlzmann distribution curve would change with an increase in temperature
-particles have more kinetic energy and move faster, many more will have energy equal/greater than Ea, shifting the curve to the right with a lower peak
Define catalyst
A catalyst is a substance that increases rate of reaction by providing an alternative reaction pathway with lower activation energy. The catalyst is unchanged
What would happen to the Maxwell Boltzmann distribution if a catalyst was used
The number of molecules with energy greater than or equal to Ea would increase
What does the peak on the Maxwell Boltzmann distribution curve represent?
This is the most likely energy of any single molecule
What does the Maxwell Boltzmann distribution represent
The distribution of kinetic energy for a certain number of molecules
Define activation energy
The minimum amount of energy needed for particles to react
Do all particles that collide react with eachother?
No
What must happen for a reaction to happen?
Particles need to collide
Define the rate of a reaction
the amount of reactant used or product formed per unit time
