The rate of a chemical reaction depends on different factors. is very fast for metals. is always the same. 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. reactive products.

4.The metal zinc is more reactive that magnesium. reacts more slowly than magnetism. is less reactive than copper. 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.

Listen 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.
