From the rater expression for the following reactions, determine their order of reaction and dimensions of the rate constants. `a. 3NO(g) rarr N_(2)O(g),` Rate`=k[NO]^(2)` `b. H_(2)O_(2)(aq)+3I^(c-)(aq)+2H^(o+) rarr 2H_(2)O(l)+I_(3)^(c-),` Rate`=k[H_(2)O_(2)][I^(c-)]` `c. CH_(3)CHO(g)rarr CH_(4)(g)+CO(g),` Rate`=k[CH_(3)CHO]^(3//2)` `d. C_(2)H_(5)Cl(g) rarr C_(2)H_(4)(g)+HCl(g),` Rate `k[C_(2)H_(5)Cl]` |

Answer» Correct Answer - `a. OR=2` `k=L mol^(-1)s^(-1)` `b. OR(H_(2)O_(2))=1` `OR(I^(c-))=1` `OR(H^(o+))=0` Overall`OR=2` `k=L mol^(-1)s^(-1)` `c. OR(CH_(3)CHO,Overall)=1.5` `k=L^(1//2) mol^(-1//2 )s^(-1)` `c. OR(CH_(2)H_(5)Cl)=1` OR(Overall)=1 `k=s^(-1)` `a.` Order with respect to `NO` and overall order `=2` `k=L mol^(-1)s^(-1)` `b.` Order `w.r.t. H_(2)O_(2)=1` Order `w.r.t. I^(c-)=1` Order `w.r.t. H^(c-)=0` Overall order order `=2` `k=L mol^(-1)s^(-1)` `c.` Order `w.r.t. CH_(3)CHO` and Overall order `=1.5` `k=L^(1//2) mol^(-1//2)s^(-1)` `d.` Order `w.r.t. C_(2)H_(5)Cl=1` Overall order `=1` `k=s^(-1)` |
