As reduction potential decreases, the change in Gibbs free energy ___. - answer
decreases
As the reaction within a voltaic cell proceeds forward, the reduction potential of
the cell ___. - answer decreases
Describe reduction potential. - answer How easily something gains electrons.
Strong IMF is associated with ___ BP/MP. - answer high
Low BP/MP is associated with ___ IMF. - answer weak
How does the concentration of the reactants affect kinetics? - answer higher
concentration = more products formed, increased likelihood of collisions
How does the temperature of the reactants affect kinetics? - answer increasing
temperature = increased kinetic energy of reactants, increased likelihood of
collisions and product formation
, How does surface area of the reactants affect kinetics? Relate this to the 3
different states/phases of matter. - answer increased surface area = greater area
for a reaction to occur, the higher the probability of a reaction and product
formation
solid > liquid > gas, in regards to probability of a reaction occurring
What order is the reaction with respect to A if the [A]t vs Time plot is linear? -
answer zero
What order is the reaction with respect to A if the ln[A]t vs Time plot is linear? -
answer 1st
What order is the reaction with respect to A if the 1/[A]t vs Time plot is linear? -
answer 2nd
How does increasing/decreasing concentration of the reactants affect
equilibrium? - answer increase reactants = shift toward product
decrease reactants = shift toward reactants
How does increasing/decreasing pressure on reactants affect equilibrium? What
state of matter does this apply too? - answer increase pressure = shift toward
product
decrease pressure = shift toward reactant
