Chemical kinetics (SCH4U) Question
and answers already assed 2025
Rates of reaction - correct answer The speed at which a chemical change
occurs. Expressed as change in concentration per unit time
Chemical kinetics - correct answer Area of chemistry that deals with rates of
reactions
AROC - correct answer Speed at which a reaction proceeds over PErIOD of
time (secant)
IROC - correct answer Speed at which a reaction is proceeding at
PARTICULAR point in time
Catalyst - correct answer A substance that alters the rate of a chemical
reaction without itself being permanently changed
Enzyme - correct answer A molecular substance in living cells that controls
the rate of a specific biochemical reaction
Factors affecting rate - correct answer Chemical nature, concentration,
temperature, catalysts, surface area
Rate law - correct answer The rate, r, will always be proportional to the
product of the initial concentrations of the reactants, where these
concentrations are raise to some exponential values.
