the half-life of the reaction, at 34 degrees celsius and Ppan=13.2 torr, is 164.0hr. Calculate the rate constant for the reaction.

confused on what to do here

What's Ppan? If this is a first order reaction, you do this.
k = 0.693/t1/2. Solve for k. If this is a second order reaction the above is not the way to go.
ok so 34+273=307
307X1/2=153.5
.693/153.5=.0045
I think its a second order reaction what do I do for that??
