Question

The following mechanism has been proposed for the conversion of ozone to oxygen in the gas phase. step 1 fast: O3O step 2 slow: 03 + 0-202 (1) What is the equation for the overall reaction? Use the smallest integer coefficients possible. If a box is not needed, leave it blank. (2) Enter the formula of any species that acts as a reaction intermediate? If none leave box blank: (3) Complete the rate law for the overall reaction that is consistent with this mechanism. Se Rate-

A student proposed the following mechanism for the gas phase reaction of fluorine with chlorine dioxide. step 1 fast 2cio, c,o, tep 2 slow: C204+F22 FCIO2 (1) What is the equation for the overall reaction? Use the smallest integer coefficients possible. If a box is not needed, leave it blank. 2 CIO2 F2 2 FCIO2+ 2) Enter the formula of any species that acts as a reaction intermediate? If none leave box blank CI204 (3) Complete the rate law for the overall reaction that is consistent with this mechanism. Use the form k[A]" [B]"..., where '1' is understood (so don't write it if it's a '1') for m, n etc. Rate k [CIO21A2 [F2]

The following mechanism has been proposed for the conversion of ozone to oxygen in the gas phase. step 1 fast: O3O step 2 slow: 03 + O-202 (1) What is the equation for the overall reaction? Use the smallest integer coefficients possible. If a box is not needed, leave it blank. 203+ 302 (2) Enter the formula of any species that acts as a reaction intermediate? If none leave box blank:O (3) Complete the rate law for the overall reaction that is consistent with this mechanism. Use the form klA] [B]"..., where 'l' is understood (so don't write it if it's a '1') for m, n etc Rate-k[031*2

The following mechanism for the gas phase reaction of nitrogen dioxide with carbon monoxide at temperatures above 225 °OC is consistent with the observed rate law. stepi fast: NO2+ CO-ONOCO step 2 slow: ONOco >NO +CO2 (1) What is the equation for the overall reaction? Use the smallest integer coefficients possible. If a box is not needed, leave it blank. NO2 +CO | NO +CO2 2) Enter the formula of any species that acts as a reaction intermediate? If none leave box blank: ONOCO (3) Complete the rate law for the overall reaction that is consistent with this mechanism. Use the form k[A]" B]"..., where '' is understood (so don't write it if it's a 'T') for m, n etc. Rate k [NO2] [CO]
