the speed with which a chemical reaction takes place.
1 of 12
Reaction Time
The time it takes for a driver to step on the break after seeing an obstacle.
2 of 12
Gradient
rate of change of two quantities on a graph; change in y/ change in x
3 of 12
Product
molecules produced at the end of a chemical reaction
4 of 12
Reactant
chemicals which are reacting together in a chemical reaction
5 of 12
Concentration
the amount of chemical dissolved in a certain volume of solution
6 of 12
Collision theory
Different reactions can happen at different rates. Reactions that occur slowly have a low rate of reaction. Reactions that happen quickly have a high rate of reaction. For example, rusting is a slow reaction: it has a low rate of reaction.
7 of 12
Catalyst
Catalysis is the increase in the rate of a chemical reaction due to the participation of an additional substance called a catalyst.
8 of 12
Relative atomic mass (Ar)
Relative atomic mass. Different atoms have different masses. Atoms have such a small mass mass: The amount of matter an object contains.
9 of 12
Relative formula mass (Mr)
To find the relative formula mass (M r) of a compound, you just add together the A r values for all the atoms in its formula.
10 of 12
Percentage yield
The yield from a chemical reaction is the mass of product made.
11 of 12
Atom economy
Atom economy (atom efficiency) is the conversion efficiency of a chemical process in terms of all atoms involved (desired products produced).
