rates of reaction Flashcards
1
Q
how can the rate of a chemical reaction be found?
A
measuring the quantity of a reactant used or the quantity of product formed over time
2
Q
what are the two different mean rate of reaction equations?
A
quantity of reactant used/time taken
quantity of product formed/time taken
3
Q
what is the quantity of a reactant or product measured by?
A
the mass in (g) or volume (cm3)
4
Q
what are the units for rate of reaction?
A
g/s or cm3/s
5
Q
what can the quantity of reactions also be given in?
A
terms of moles and the unfits for rate is mol/s
6
Q
what factors affect the rate of chemical reactions?
A
- concentration of reactant
- pressure of reacting gas
- surface area of solid reactants
- temperature
- presence of a catalyst
