(a)

Interpretation Introduction

Interpretation:

The equation for the overall reaction has to be given.

(b)

Interpretation Introduction

Interpretation:

The structural formulas for all the given species has to be given.

(c)

Interpretation Introduction

Interpretation:

From the given reaction, the rate determining step has to be identified.

(d)

Interpretation Introduction

Interpretation:

Whether the given reaction is endothermic or exothermic has to be checked.

Concept introduction:

Exothermic reaction:

If heat is released during a chemical or physical change those reactions are called as exothermic reactions.

Example:CH4(g)+2O2(g)CO2(g)+2H2O(l)+890kJInthisreaction890kJofheatisreleased.

Endothermic reaction:

If heat is absorbed during a chemical or physical change those reactions are called as endothermic reactions.

Example:Ba(OH)2(aq)+2NH4NO3(aq)2NH3(g)+2H2O(l)+Ba(NO3)2Inthisreaction170.8kJofheatisabsorbed.

(e)

Interpretation Introduction

Interpretation:

1. Which of the following statements is incorrect? (A) As the chemical reaction proceeds, the rate of reaction increases. (B) The reaction rate almost gets doubled for 10°C rise in temperature. (C) For a first order chemical reaction, the rate constant has unit of time-1. (D) Chemical kinetics can predict the rate of a chemical reaction. 2. In a chemical reaction, represented by A → P, it is observed that the rate of reaction increases by a factor of 4 on doubling the concentration of the reactant. The rate of reaction increases by a factor of 9 on trebling the concentration of the reactant. Then the rate of the reaction is proportional to (A) CA (B) CA2 (C) CA3 (D) CA4 3. An elementary reaction has the stoichiometric equation A + 2B = P. What is the order of reaction (A) 0 (B) 1 (C) 2 (D) 3 4. It states that the rate of a chemical reaction is directly proportional to the product of the activities or concentrations of the reactants. (A) Law of mass action…
(a) Select all of the correct statements about reaction rates from the choices below. The lower the rate of a reaction the longer it takes to reach completion.Reactions involving very unstable combinations of chemicals have large rate constants.Concentrations of homogeneous catalysts have no effect on reaction rates.Reaction rate constants are independent of temperature.The slowest step in a reaction is called the rate-determining step.A balanced chemical reaction is necessary to relate the rate of reaction to the concentration of a reactant.Slow reactions can be speeded up by raising the temperature.
For the reaction: 2N205(g) -->4NO(g) + O2(g) (a) write the mathematical rate expression in terms of (i) the disappearance of N2O5 (Reactant); (ii) the formation of NO (Product); (iii) the formation of O2 (Product). (b) What are the stoichiometric relationships (rationalization) of the various rates for this reaction? (e.g. Product C formation is 2x faster than Reactant A disappearance/decomposition.)
