10. Reaction Rates and Equilibrium Flashcards
1
Q
How can you follow the progress of a reaction?
A
monitor decr. in conc. of a reactant
follow incr. in conc. of a product
2
Q
What is the equation for rate?
A
rate = change in conc/time
3
Q
What are the conditions for an effective collision?
A
particles collide in correct orientation and have energy greater than the required activation energy
4
Q
What factors alter the rate of a chemical reaction?
A
surface area (solids) concentration (liquids) pressure (gases) temperature catalyst
5
Q
Why does increasing concentration or pressure increase rate of reaction?
A
increased no. particles in the same volume
particles are closer and collide more frequently
therefore there are more frequent successful collisions and a higher RoR
