Question

QUESTION 6

Consider the reaction below at 100oC.

T2U  (g)   ->  2 T (g)   +  U (g)

When [T2U]o is 0.250 M, the reaction rate is 9.30 x 10-3 M/s, and when [T2U]o is 0.144 M, the reaction rate is 3.09 x 10-3 M/s.  If the reaction has an activation energy of 66 kJ/mol, what is the numerical value of the rate constant at 25oC?  Please assume k has the same units as those you selected for Question 3.

 A.    0.000703 B.   0.00472 C.   0.0373 D.   0.117
Step 1

Arrhenius equation gives the effect of change of temperature on the reaction rate constant.

Step 2

For two different tempeartures, the equation is modified as:

Step 3

Using the concentration of the reactant and rate of the reaction, the order of...
