ln [1.70E2] = ln(0.144)  (k s1)(3609 s)
Solve for k.
I have a TI30 calculator. Am I suppose to press just the ln button or do I have to press 2nd and then ln??

If you know what the formula is, but can't figure out which buttons to press, I suggest that you sit down with your calculator manual and spend a few days going through the examples they will surely have.
I remember when I got my first slide rule. *gasp* I spent two weeks just going through the manual. After that, I knew the machine inside and out.
