Properties of light lab report
be sure to identify the test variable (independent variable) and the outcome variable (dependent variable) for this investigation. remember, the test variable is what is changing in this investigation. the outcome variable is what you are measuring in this investigation.
test variable (independent variable):
outcome variable (dependent variable):

adding or remove a gaseous reactant or product changes the concentrations. if the concentration of reactant or product is increased, the system will shift away from the side in which concentration was increased (i.e. if the concentration of reactants is increased, the system will shift toward the products. if more products are added, the system will shift to form more reactants). conversely, if the concentration of reactant or product is decreased, the system will shift toward the side in which concentration was decreased (i.e. if reactants are removed, the system will shift to form more reactants. if the concentration of products is decreased, the equilibrium will shift toward the products).
