Reactants
________ are transformed into products in a chemical reaction by definition.
New cards
3
O3
Most collisions between NO and ________ molecules in the reaction vessel contain only enough energy for the molecules to bounce off one other without reacting.
New cards
4
Physical state
________ influences rate by determining how well reactants can mix.
New cards
5
Humans age
________ over decades, and coal is formed from dead plants over hundreds of millions of years.
New cards
6
Temperature
________ influences reaction rate by increasing collision frequency and, more crucially, collision energy: The frequency with which collisions occur.
New cards
7
influences rate
Concentration ________ by influencing the frequency and, more importantly, the energy of collisions between reactant molecules.
New cards
8
response rate
Knowing the ________ is important because how quickly a drug acts may mean the difference between life and death, and how long it takes a commercial product to develop can be the difference between profit and loss.
New cards
9
Chemical kinetics
________, the study of how quickly change happens, focuses on the reaction rate, or the change in reactant (or product) concentrations as a function of time.
New cards
10
Physical state
________: In order for molecules to collide, they must first mix.
New cards
11
influences rate
Temperature ________ by influencing the frequency and, more importantly, the energy of collisions between reactant molecules.
