Lone pair of electrons on oxygen in one molecule is attracted to H with δ+
charge in the other molecule (2 marks)
1 of 4
Instantaneous dipole - induced dipole
How it arises:
electron movement in molecules creates an uneven distribution of charge leading to temporary dipole
A dipole is induced in neighbouring molecules leading to attraction (2 marks)

Differences between Silicon Oxide and Carbon Dioxi
Sio2= giant covalent structure, or whole structure held together by covalent bonds
CO2= simple molecular
comparison= weak intermolecular bonds or forces in CO2 so less energy is needed to separate molecules bonds in SiO2are stronger than CO2intermolecular bonds (or forces)

Effect of temperature on the rate of reaction
Rate is higher when the temperature is higher
Particles have more energy so they move around faster
there are more frequent collisions
More particles have the total energy of at least the activation energy
