How can you follow the progress of a reaction?
monitor decr. in conc. of a reactant follow incr. in conc. of a product
What is the equation for rate?
rate = change in conc/time
What are the conditions for an effective collision?
particles collide in correct orientation and have energy greater than the required activation energy
What factors alter the rate of a chemical reaction?
surface area (solids) concentration (liquids) pressure (gases) temperature catalyst
Why does increasing concentration or pressure increase rate of reaction?
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
