18 rates of reactions Flashcards
1
Q
half-life
A
time taken for the concentration of a reactant to decrease by half
2
Q
initial rate of reaction
A
change in concentration of reactant or product per unit time at the start of the reaction, t=0
3
Q
order
A
power to which the concentration of a reactant is raised in the rate equation
4
Q
overall order
A
sum of the individual orders of reactants in the rate equation
5
Q
rate constant, k
A
constant that links rate of reaction with concentrations of the reactants raised to the powers of their orders in the rate equation
6
Q
rate determining step
A
slowest step in the reaction mechanism of a multi step reaction
