Factors that determine whether exposure to a chemical will have a toxic effect include the toxicity of the chemical, the dose or amount of the chemical to which a person is exposed, the duration of exposure, the route of exposure (e.g. inhalation, ingestion, dermal contact), individual characteristics (e.g. age, sex, genetics), and pre-existing health conditions.
The participation of reactants in a chemical reaction is restricted by factors such as activation energy, steric hindrance due to molecular size, and the nature of the chemical bonds present. These factors can determine whether a reaction will proceed and at what rate.
The factors that determine whether a chemical reaction will proceed in an energetically favorable or unfavorable direction include the difference in energy between the reactants and products (enthalpy change), as well as the entropy change and temperature of the system. If the overall change in energy is negative (exothermic) and the increase in disorder (entropy) is positive, the reaction is likely to proceed in a favorable direction.
To determine whether a chemical reaction occurred, you will need data such as changes in temperature, formation of new substances, release of gas, and changes in color or odor.

The factors that determine whether a person can be eligible for an artificial heart include a failed heart, and a physically damaged heart.
Factors that determine a chemical change include the types of substances involved, the presence of a catalyst, temperature, pressure, and concentration of reactants. Additionally, the activation energy required for the reaction to occur also plays a significant role in determining whether a chemical change will take place.
