Слайд 3The rate of a chemical reaction
depends on different factors.

2. In order for a chemical reaction to occur
the volume of a gas must increase.
solids must be compressed.
molecules must collide.
3. Higher concentrations of reacting substances will lead to
more chemical reactions.
increased pressure.

5. Higher temperature can make molecules
Travel faster with no increase in energy.
Travel at the same speed, but with more energy.
Travel faster, and with more energy.

Слайд 5Listen to two students talking about chemical reactions. Then decide if
the following statements are true or false.
A chemical reaction begins with reactants.
Weight is released in a chemical reactions.
Salt is a metal.
Sodium and chlorine are solids.
In a chemical reaction combined substances make new ones.
