Chemical equations Flashcards
Chemical Equation
uses chemical formulas and other symbols showing what reactants are the starting materials in a reaction and what products are formed
Reactants
written to the left
products
written on the right
Coefficients
they show the number of molecules of a given element or compound that react or are formed
What does a chemical reaction involve?
- breaking bonds in the reactants
- forming new bonds in the products
What happens if the activation energy is low?
The reaction will be fast
Effects on equilibrium (e)
adding reactant = e will favor products
removing reactant = e will favor reactants
adding product=e favors reactants
removing product= e favors products
Increasing temperature
in an endothermic reaction, e favors the products. in an exothermic reaction e favors the reactants
Decreasing temperature
In an endothermic reaction, e favors the reactants. In an exothermic reaction e favors the products
