From the diagram, when the temperatures of reactants are raised from 20°C to 30°C:
The average kinetic energy doubles.
The number of molecules doubles.
The total number of collisions doubles.
The number of molecules having E, or greater doubles,

4. propanol and isopropanol are isomers. this means that they have a) the same molecular formula but different chemical properties. b) different molecular formulas but the same chemical properties. c) the same molecular formula and the same chemical properties. d) the same molecular formula but represent different states of the compound
