The specific rate constant for the first-order decomposition of N2O5(g) to NO2(g) and O2(g) is 7.48×10−3s−1 at a given temperature. 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 0.220 atm .
Solutions
Expert Solution
Initial 0.100 0 0
Final (0.100-x) 2x 0.5x
Final Pressure = (0.100-x) + 2x + 0.5x = 0.100 + 1.5x = 0.220
1.5x = 0.120
x = 0.080
For the first order decomposition
Ao = 0.100 atm, At = 0.020 atm
ln(Ao/At) = kt
ln(0.100/0.020) = (7.48 * 10^(-3)) * t
t = 1000 * ln(5)/7.48 = 215.165 seconds
