Fire ventilation means that fire gases must be vented out, but also that fresh air will flow in (generally). This supply of air normally affects the fire in such a way that the rate of heat release from the fire increases or the fire spreads faster.

The rate equation shows the effect of changing the reactant concentrations on the rate of the reaction. All other factors affecting the rate—temperature and catalyst presence, for example—are included in the rate constant, which is only constant if the only change is in the concentration of the reactants.

Factors Determining the Cooling Rate. The four most important factors determining the actual cooling rate are the type of quenching medium, the temperature of the quenching medium, the surface condition of the part and the size and mass of the part.

Population growth is based on four fundamental factors: birth rate, death rate, immigration, and emigration.

Glow Sticks and the Rate of Chemical Reaction Several factors affect the rate of a chemical reaction, including temperature, concentration of reactants, and the presence of other chemicals.

The temperature and concentration are factors that affect the magnitude. An increase in temperature increases the rate constant and hence the rate. An increase in concentration increases the rate but not the rate constant. the rate of a reaction depends on the rate constant and concentration.
