The first-order rate constant for the decomposition of dimethyl ether (CH3)2O(g)> CH4(g)+H2(g)+CO(g) is 3.2104s1 at 450C. The reaction is carried out in a constant-volume flask. Initially only dimethyl ether was present, and the pressure was 0.350atm. Assume ideal behavior. (a) What is the gas concentration (n/V) of dimethyl ether after 10.0min ? (Hint: n/V= P/RT) The answer is _ 103 (answer format:_._) The first-order rate constant for the decomposition of dimethyl ether (CH3)2O(g)> CH4(g)+H2(g)+CO(g) is 3.2104s1 at 450C.
