a. 2 BF3 → B2F6
B2F6 + NH3 → BF3 + F3BNH3
-------------------------------------------------
2 BF3 + NH3 → BF3 + F3BNH3
b. The rate determining step is the slow step.
c.rate = k(BF3)^2( NH3)
d. The intermediate is the "compound" that is canceled when the equations are added; i.e., B2F6
B2F6 + NH3 → BF3 + F3BNH3
-------------------------------------------------
2 BF3 + NH3 → BF3 + F3BNH3
b. The rate determining step is the slow step.
c.rate = k(BF3)^2( NH3)
d. The intermediate is the "compound" that is canceled when the equations are added; i.e., B2F6
