ln(Po/P) = kt
Po = initial P
P = final P. Solve for this.
k = given
t = given
The decomposition of sulfuryl chloride (SO2Cl2) is a first-order process. The rate constant for the decomposition at 660 K is 4.5 10-2 s-1.
(a) If we begin with an initial SO2Cl2 pressure of 425 torr, what is the pressure of this substance after 74 s?
what is the equation to solve this?

i got 11873 which seems kinda high..?
is k negative because of the s-1?
without making it negative i got 15.21 which seemed more reasonable but when i plugged it in it was wrong

k is not negative.
I obtained 15.23. How is the problem stated? If k = 4.50E-2 then you are allowed three significant figures and you should report 15.2 and the data base is counting it wrong because you are using too many places. If k = 4.5E-2 you are allowed only two significant figures and you should report 15.

i just tried that and it is wrong.
does the temperature it gives have anything to do with the problem?
The correct answer is 15 torr.
Does the problem as for P in torr or some other unit?
