Study Set Content:
a temperature increase favors an
endothermic reaction
a temperature decrease favors an
exothermic reaction
right
the amounts of products are increased at equilibrium by an increase in temperature
For an endothermic reaction
no effect
According to Le Chatelier’s principle, as the temperature is raised, the reaction
shifts to form more reactants, thereby absorbing heat and “attempting” to counter the increase in temperature.
is a substance that increases the rate of a reaction but is not consumed by it.
Catalyst
is the time required for one-half of a given amount of reactant to be consumed.
half-life of a reaction
In each succeeding half-life,
half of the remaining concentration of the reactant is consumed.
do not affect equilibrium
• Catalysts
are biological catalysts
Enzymes
a compound that accepts a proton (proton acceptor)
Bronsted-Lowry base
is a substance that, when dissolved in water, increases the concentration of hydronium ion, H3O(aq).
acid(Arrhenius)
a species that can form a covalent bond by donating an electron pair to another species
Lewis base
conjugate acid
can be devised using the negative logarithm of the hydroxide ion concentration of a solutio
pOH scale
an acid and its conjugate base or a base and its conjugate acid
Conjugate acid-base pair:
acid
Acidic
Neutral
