Which choice gives correct kinetics information for thisreaction?   Which choice is closest to the rateconstant for this reaction?  Which choice is closest tothe missing initial rate for Exp’t 5?

1st-order wrt A; 2nd-overall    

k = 50.0 Lmol–1s–1    

0.00400 mol∙L-1s-1    

1st-order wrt A; 1st-order wrtB      

k = 2.5 Lmol–1s–1    

0.200 mol2L–2s–1    

2nd-order wrt B; 3rd-order overall  

k = 50.0 L2mol–2s–1    

0.900 mol∙L-1s-1      

2nd-order wrt B; 1st-order wrt C    

k = 25 L2mol–2s–1    

0.200 mol∙L-1s-1
