rate of reactions

chemical kinetics

the area of chemistry that focuses on how
fast a reaction can occur.

rate of reaction

a measure of how quickly reactants are converted into products in a chemical reaction.

rate of reaction

the change in the concentration of reactants or products over time.

catalyst

are substances that hasten reaction
without themselves being consumed in the reaction.

spontaneity

the property of a process to
occur without an external input of energy.

spontaneity of a reaction

refers to whether a reaction will occur naturally without any external intervention.

spontaneous process

When a system undergoes a change in one direction under a given set of conditions

nonspontaneous process

is the reverse reaction is the process of manufacturing iron from iron ore.

entropy

a thermodynamic property that describes how the energy of a system is distributed among its available microscopic energy levels.

S

entropy is denoted by the letter

high entropy

when the system is more disordered it has?

lower entropy

when a system is more ordered it has?
