Answer #1

The rate constant of a reaction is 4.5*10-5 L/mol*s at 195°C and
3.20*10-3 L/mol*s at 258°C. What is the activation energy of the
reaction? If this is a 2nd order reaction, what would the axes of a
graph that shows its concentration change as a linear function?

The rate constant of a reaction is 7.55 × 10−5 L/mol·s at 195°C
and 7.75 × 10−3 L/mol·s at 258°C. What is the activation energy of
the reaction?

The rate constant of a reaction is 6.7 ×
10−3 s−1 at
25°C, and the activation energy is
33.6 kJ/mol.
What is k at 75°C? Enter your
answer in scientific notation.

If the rate constant k of a reaction doubles when the
temperature increases from 121 °C to 279 °C, what is the activation
energy of the reaction in units of kJ/mol? Do not enter units with
your numerical answer. Do not use scientific notation.

The rate constant for a reaction was determined to be 4.25 * 10
^ -3 L/mol*s at 22.5 C. The rate constant was then measured at 48.0
C and found to be 1.95 * 10 ^ -2 L/mol*s. Calculate the value of
the activation energy. Is the reaction first of second order?
PLEASE EXPLAIN THIS AS MUCH AS POSSIBLE INCLUDING EVERY LITTLE
STEP IN THE ANSWER. Thank you so much!

￼A second‐order reaction was observed. The reaction rate
constant at 3 °C was found to be 8.9 x 10‐3 L/mol and 7.1 x 10‐2
L/mol at 35 °C. What is the activation energy of this reaction?
￼

The rate constant of a first-order reaction is 0.0032 x
10-4 L/mol *s at 640 K. If the activation energy is
176,406J/mol, calculate the temperature at which is rate constant
is 0.0039 x10 -4 L/mol*s.
Show your work please.

The activation energy (E*) for a reaction is 195 KJ. If the k
for this reaction is 3.46 x 10-5/min at 35oC, what will the
temperature be in OF when k is 1.5 x 10-3/min? If this
was a second order reaction, what are the half life’s at each
temperature?

A reaction has a rate constant of 1.26×10−4 s−1 at 28 ∘C and
0.233 s−1 at 79 ∘C .
1.Determine the activation barrier for the reaction. Express
your answer in units of kilojoules per mole.
2. What is the value of the rate constant at 17 ∘C ? Express
your answer in units of inverse seconds.

the rate constant for the reaction shown below is 2.6x10^-8
L/mol*s when the reaction proceeds at 300K. The Activation Energy
is 98000J/mol. Determine the magnitude of the frequency factor for
the reaction. If the temperature changed to 310K, there rate
constant would change. The ration of K at 310 K is closest to what
whole number?
