Question

Will medal and fan!!!!!!!





The specific rate constant for the first order decomposition of N2O5 to NO2 and O2 is 7.48*10^-3 s^-1 at a given temperature.
a) Find the total pressure after 110s of reaction.
b) Find the length of time required for the total pressure in a system containing N2O5 at an initial pressure of 0.100 atm to rise to 0.155atm. (ANS: 61s)
c) Find the length of time required for the total pressure in a system containing N2O5 at an initial pressure of 0.100 atm to rise to 0.200 atm. (ANS: 150s)

I just need help with part (a) please!
