Question

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.  What are the units for the specific-rate constant, k? 


What are the units of the specific-rate constant, k

   

A.     L2  mol-1  s-1

   

B.  s-1

   

C.   mol L-1  s-1

   

D.     L mol-1 s-1
