chapt 14 (rate of reaction)

Question 1

How to measure ROR? (2)

Answer 1

• volume of gas produced (conical flask gas syringe)
• change in mass (electronic balance)

Question 2

what affects ROR? (5)

Answer 2

• Conc. of reactants - (no. of reacting particles per unit vol increases, collide freq. , inc. freq of effective collision)
• Pressure (less space for particle to move arnd, collide more freq, inc. freq of effective collision)
• Particle size (inc. of surface area)
• Temperature (inc. in kinetic energy)
• Catalyst (inc rate of reaction without changing the substance)
