Question
(a) Because Arrhenius equation contains the gas constant R, the Arrhenius equation applies only to gas-phase reactions (b) The Arrhenius equation holds exactly. (c) The pre-exponential factor A has the same units for all reactions. (d) In homogeneous catalysis, the catalyst does not appear in the rate law. (e) In homogeneous catalysis, doubling the catalyst concentration will not change the rate (f) A catalyst does not appear in the overall reaction. (g) In homogeneous catalysis, the catalyst does not appear in any of the steps of the mechanism.Explanation / Answer
d. True because in homogeneous catalysis generally the rate equation is created to eastablish a relation between rate and reactant concentration so the dependency catalysis concentration is not needed.
f.True . g. false because, a catalyst is a substance that speeds up the rate of chemical reaction but is not consumed in the course of reaction. A catalyst will appear in the steps of a reaction mechanism but will not appear in the overall chemical reaction as it is not a reactant or product.
e. False If we double or increase the catalyst concentration the reaction rate will increases up to some mark and will be constant.
c. False . the units of pro exponential factor will vary depend on the order of the reaction.
a.False . It is not exactly restricted to gas phase only but generally they denote like that because in gas phase reactions take place very fastly when compared to other phases where we have to find some complications suring other phases
