自然科學 大學 3個月以前 這兩題該怎麼寫 5. Suppose that a reaction C2H6C2H4+H2 is believed to occur by the mechanism: 1. C2H6-2CH3 2. CH3+ C2H6 CH4+ C2H5 ->> 3. C2H5 C2H4+H 4. C2H6+H→C2H5+H2 5. 2 C2H5 C4H10 . Apply the steady-state treatment to C2H5 CH3 Hand obtain an expression for the overall rate. 6. The reaction between chlorine and chloroform in the gas phase follows the stoichiometric equation CHC13 C12 CCl4 + HCl It is believed to occur by the mechanism Cl₂+hv 2C1 Cl+CHCl3 HCl + CC13 CC13 C12 CCl4 + Cl 2C1→Cl₂ Assume that the steady-state treatment can be applied to C1,CC13 and obtain an expression for the overall rate. 待回答 回答數: 0
