Explanation / Answer

This one looks trickier at first glance but it is really stratforward. The rate changes with the same proporcion of eachreactant this means that the rate is dependant on both in a one toone ratio. When claculating this make sure you use thedifference where the concentration of the of the reactant isconstant. A.Rate=k*[BF3] *[NH3] B. this is a second order raction because there are two factorin the rate equation. C. You any values from the row to find the rateconstant. .2130=k*.25*.25 k=3.408 D. rate=3.408*.1*.5 rate=.1704
