15.63 units and reaction order

[Angela G 2K]

The question gives the rate constant 25 C as 1.5x10^10 L.mol-1.s-1, indicating a second order reaction. The question asks for the rate constant of the same reaction but at 37 C, given an activation energy of 38 kJmol-.1. The answer I got was 2.7x10^10 L.mol-1.s-1, but the answer in the back of the book is 2.7^10 mol.L-1.s-1, indicating a zero order reaction. How does this happen?

Thanks in advance!

I'm pretty sure you are correct with the units. I got L mol-1s-1 as well for the units!
