Topic 5 and 6 Definitions UwU Flashcards
half life
the time it takes for an isotope to half its radioactive value
rate determining step
the slowest step of a reaction that determines the role of the overall reaction
mole fraction
the proportion of moles of one component of a solution/mixture to the total no. of moles of all the components
partial pressure
hypothetical pressure a constituent gas had if alone at the same volume and temperature
rate of reaction
rate at which chemical reactions proceeds (duh)
order
the relationship between concentration of the reactant and its effect on the rate of reaction
overall order
the sum of the orders of every reactants in a reaction
rate constant
constant that expresses the relationship between the rate of a reaction and the concentrations of the reactants
acid
proton donor (i thought it was burning-y stuff lol)
base
proton acceptor
conjugate acid-pairs
two substances in a reaction that differ only by a proton
monobasic acids
acid that only donates one proton
dibasic acids
acid that only donates 2 protons
lattice enthalpy
enthalpy change when one mol of ionic lattice is formed from gaseous ions (ΔHce). Used to measure strength of ionic bonds in the giant ionic lattice)
oxidising agent
substance that can oxidise other substances by accepting their electrons
reducing agent
substance that can reduce other solutions by donating its electrons
lingard
an ion/molecule that binds to a central metal atom/ion to form a complex
complex ion
metal atom/ion at the centre of a complex
coordination no.
no. of atoms/ions/molecules (species) bonded to the central atom ion in a complex
standard electrode (redox) potential
the emf measured when you conect a half cell to a H half cell under standard conditions
entropy
(S) quantitive measure of disorder in a system
optical isomerism
type of stereo isomerism relating to non-superimposable mirror images about a chiral centre
