A
Concentration, pressure, surface area, catalysts, temperature.
4
Q
what is concentration
A
a measurement of the number of particles dissolved in a given volume of solvent
5
Q
What is pressure
A
a measurement of the number of particles in a given volume of gas.
6
Q
what is a catalyst
A
a substance that speed up a chemical reaction without being used up. it works by lowering the activation energy for the reaction.
