Chem 116 Final Exam 2025 update|comprehensive
questions and verified answers (complete solutions)
ASSURED SUCCESS|GRADE A+!! ( 100% ACCURATE)
GET IT RIGHT!!
Factors that Affect the rate of the reaction: - (answer)physical state of the
reactants.
concentration of the reactants.
temperature of the reaction.
presence or absence of a catalyst.
(Collision energy, collision frequency, collision orientation)
In a rate expression... - (answer)the products will be positive and the reactants
will be negative
Intermediate - (answer)is first produced, then used as a reactant
Catalyst - (answer)CRP, reactant than product
First Order - (answer)s^-1
Second Order - (answer)M^-1 s^-1
Third Order - (answer)M^-2 s^-1
, 2|Page
Rate Determining Step - (answer)slowest reaction of a chemical reaction
Catalyst... - (answer)Will not change the equilibrium of the reaction (changes the
Ea of both the forward and reverse reactions). It gives an alternate pathway that
requires less energy
Collision Theory - (answer)1- Collision
2- Proper Orientation
3- Sufficient Energy
Arrhenius Equation - (answer)increase in temp will increase K
decrease in Ea will increase K
What increases K? - (answer)increase in Temperature and decrease in Activation
Energy
Decreases K? - (answer)Increase in Ea, decrease in T
What increases the Rate? - (answer)Temperature, decrease in Ea and increase in
reactants
Activation Energy - (answer)the lower the Ea the faster the reaction rate
