Accompanying Lesson Plan: Lesson 6.2: Controlling the Amount of Products in a Chemical Reaction Adding more of one reactant will make more products as long as there is still enough of the other ...

The speed of a chemical reaction is affected by temperature, concentration, particle size and the presence of a catalyst. It can be calculated by measuring changes in reactants/products.

In the reaction for an exothermic reaction, the overall change is negative. You can tell this because the products have less energy than the reactants, and the arrow showing the overall change in ...
