15. Chemical Kinetics
Half-Life
Methane and propylene are produced when butane undergoes gas-phase thermal decomposition.
C4H10(g) → C3H6(g) + CH4(g)
Butane is introduced into a furnace at a pressure of 30 torr. How many seconds are required for the pressure of CH4 to reach 6.5 torr? The half-life for this reaction is 3.0×103 s. Assume a first-order reaction.
