Consider the homogeneous reaction between sulfur vapor and methane to form carbon disulfide this elementary reaction has been studied experimentally in a small tubular reactor with a 35.2 cm3 volume. in a particular steady state run at 600 °c and 1 atm, a total of 1.32 mmol of cs2 were collected from the reactor outlet during 10 min of operation. the feed consisted of 4 mmol of s2/min plus a stoichiometric amount of ch4 find the rate constant (k) for the reaction at 600 °c assume: plug flow, ideal gas, isothermal operation
