The equation
describes the relationship of he distance traveled and the time elapsed as one object travels a specified distance. This means that when t is 2 then d is 80. You know that a car is still in the air when the distance is a positive number and zero. The equation only holds true when t is at 0 to 3.
True
Explanation:
Reaction rates are defined as the change in the concentration of a reactant or product per unit time. During a reaction, the concentration of a reactant decreases exponentially with time while that of a product increases exponentially with time.
Some of the factors affecting reaction rates are:
- Nature of the reactants
- Concentration of the reactants or pressure of gases
- Temperature
- Presence of a catalyst
- Sunlight
- The rate of a reaction is directly proportional to the concentration of the reactants.
- The higher the concentration of a reaction, the faster it proceeds.
