Flashcards in Chem1 Deck (12):
What does "rate of reaction mean"?
The speed of a reaction
What is needed for a reaction to occur?
Particles to collide with a certain amount of energy
How does increasing the temperature, increase the rate of reaction?
It gives the particles more kinetic energy which means a higher chance of collisions with larger energy, leading to the rate of reaction increasing.
What is the effect of concentration on the rate of reaction?
Increasing concentration, increases the rate of reaction. We had more acid molecules within the same volume so greater chance of collisions.
What does a catalyst do?
Speed up chemical reactions without getting involved or used up within the process/reaction
How does a catalyst speed up a chemical reaction?
By lowering the energy needed for a chemical reaction to be activated. Activation energy is less with catalyst
What type of energy is needed for a reaction to occur?
How does surface area effect the rate of reaction?
The larger the surface area, the faster the rate of reaction. This is because there will be more particles exposed to the other reactant to react with
What does a metal carbonate and acid produce?
A salt, water and carbon dioxide
What does a metal oxide and acid produce?
A salt and water
What does a metal and acid produce?
A salt and hydrogen
