Exercise 4
Hints
- What are the electron arrangements of these atoms/ions?
- a) remember, rate = change in mass or vol./change in time; bi) Would this be more or less acid in total? What effect would this have on the no. moles (vol.) of gas produced? ;bii) What effect would this have on the no. moles (vol.) of gas produced?
- Particles need to collide to react. What about the energy of this collision? What about the orientation of the molecules?
- a) Activation energy = peak energy-energy of reactants; b)Enthalpy change = energy of reactants – energy of products; c)Google this!; d) Catalysts lower the activation energy…
- What is an isotope?
