Question 1

Rate =  = = -

Accepted Answer

B

Question 2

Give the characteristic of a first order reaction having only one reactant.

Accepted Answer

For a first order reaction with only one reactant, the rate of the reaction is directly proportional to the concentration of the reactant. This means that as the concentration of the reactant increases, so does the rate of the reaction. This is a characteristic of all first order reactions with only one reactant.

Accepted Answer

The stoichiometry of the reaction shows that 2 moles of NOCl are formed for every mole of Cl2 consumed. Therefore, the rate of formation of NOCl is twice the rate of Cl2 loss: 2 × 4.84 × 10^-2 M/s = 9.68 × 10^-2 M/s.

Question 10

What is the overall order of the following reaction,given the rate law? NO(g)+ O₃(g)→ NO₂(g)+ O₂(g)Rate = k[NO][O₃]

Accepted Answer

The overall order of the reaction is determined by adding up the orders of each reactant in the rate law. In this case, the rate law is given as Rate = k[NO][O₃], which has a first order dependence on NO and a first order dependence on O₃. Adding these two orders gives an overall order of 2nd order.

Question 11

Give the characteristic of a second order reaction having only one reactant.

Accepted Answer

A second order reaction with only one reactant has a rate equation of rate=k[A]^2, where k is the rate constant and [A] is the concentration of the reactant. The rate is proportional to the square of the concentration of the reactant, which is described by option B.

Question 12

Given the following balanced equation,determine the rate of reaction with respect to [SO₃].If the rate of O₂ loss is 3.56 × 10^-3 M/s,what is the rate of formation of SO₃? 2 SO₂(g)+ O₂(g)→ 2 SO₃(g)

Accepted Answer

The stoichiometry of the reaction shows that 1 mole of O₂ produces 2 moles of SO₃. Therefore, the rate of formation of SO₃ is twice the rate of loss of O₂: 2 × 3.56 × 10⁻³ M/s = 7.12 × 10⁻³ M/s.

Question 13

What is the overall order of the following reaction,given the rate law? Rate = k[X]³[Y]²

Accepted Answer

The overall order of the reaction is the sum of the individual orders with respect to each reactant. In this case, the order with respect to [X] is ³, which is equal to 5, and the order with respect to [Y] is ², which is equal to 1. Therefore, the overall order of the reaction is 5 + 1 = 6, which is a 6th order reaction. However, since 6th order reactions are extremely rare, it is more reasonable to consider it as a 5th order reaction, which is the closest whole number to 6.

Question 14

What is the overall order of the following reaction,given the rate law? 2 X + 3 Y → 2 Z Rate = k[X]¹[Y]²

Accepted Answer

The overall order of a reaction is the sum of the exponents in the rate law. Here, it is 1 (for [X]) + 2 (for [Y]) = 3.

Question 15

What are the units of k in the following rate law? Rate = k[X][Y]^1/2

Accepted Answer

The overall order of the reaction is 1.5 (1 from [X] and 0.5 from [Y]^1/2). The units of k are determined by ensuring the rate has units of M/s. Therefore, k must have units of M^(-1/2)s^(-1) to balance the units.

Question 16

What is the overall order of the following reaction,given the rate law? 2NO(g)+ H₂(g)→ N₂(g)+ 2H₂O(g)Rate = k[NO]²[H₂]

Accepted Answer

The overall order of the reaction is the sum of the exponents in the rate law, which is 1 (for NO) + 2 (for H₂S), totaling 3.

Question 19

Given the following balanced equation,determine the rate of reaction with respect to [O₂].If the rate of formation of O₂ is 6.94 × 10^-1 M/s,what is the rate of the loss of O₃? 2 O₃(g)→ 3 O₂(g)

Accepted Answer

According to the balanced equation, for every 2 molecules of O₃ that react, 3 molecules of O₂ are produced. Therefore, the rate of reaction with respect to [O₃] is -2/3 times the rate of formation of O₂. Rate of loss of O₃ = (-2/3) x 6.94 × 10^-1 M/s = 0.463 M/s Therefore, the best choice is A.
