Cyclopropane (c₃h₆) reacts to form propene (c₃h₆) in the gas phase. the reaction is first order in cylclopropane and has a rate constant of 5.87×10⁻⁴s⁻¹ at 485 °c .
If a 2.8 -L reaction vessel initially contains 723 torr of cyclopropane at 485 °C, how long in minutes will it take for the partial pressure of cylclopropane to drop to below 105 torr?
