How are half reactions combine to give overall redox reaction

Chemistry
1 answer:
Bad White [126]3 years ago
5 0

Answer:

the oxidized substance will have electrons as products (i think)

Explanation:

The first step to balance any redox reaction is to separate the reaction into half-reactions. The substance being reduced will have electrons as reactants, and the oxidized substance will have electrons as products. (Usually all reactions are written as reduction reactions in half-reaction tables.

Can someone help?? This is really hard.
Sergeu [11.5K]

Answer:

See Explanation

Explanation:

Let us consider the first two reactions, the initial concentration of CO was held constant and the concentration of Hbn was doubled.

2.68 * 10^-3/1.34 * 10^-3 = 6.24 * 10^-4/3.12 * 10^-4

2^1 = 2^1

The rate of reaction is first order with respect to Hbn

Let us consider the third and fourth reactions. The concentration of Hbn is held constant and that of CO was tripled.

1.5 * 10^-3/5 * 10^-4 = 1.872 * 10^-3/6.24 * 10^-4

3^1 = 3^1

The reaction is also first order with respect to CO

b) The overall order of reaction is 1 + 1=2

c) The rate equation is;

Rate = k [CO] [Hbn]

d) 3.12 * 10^-4 = k [5 * 10^-4] [1.34 * 10^-3]

k = 3.12 * 10^-4  /[5 * 10^-4] [1.34 * 10^-3]

k = 3.12 * 10^-4/6.7 * 10^-7

k = 4.7 * 10^2 mmol-1 L s-1

e) The reaction occurs in one step because;

1) The rate law agrees with the experimental data.

2) The sum of the order of reaction of each specie in the rate law gives the overall order of reaction.

Fill in the blanks below using vocabulary terms-reactants, products, limiting reactant, excess reactant.
slamgirl [31]

Answer:

The vocabulary terms are in the correct order.  

Explanation:

The substances that undergo chang are called <em>reactants</em>. They are what create the products. Reactants are on the left side of the equation while the products are on the right side of the equation. The new substances are called <em>products</em>. In other words, what is produced? The products are produced. The reactant that will be used up first is called a <em>limiting reactant</em>. Why? Because it is what limits the reaction. It determines how much products can be made. The reactant that is left over then, is called the <em>excess reactant.</em> That is what is left in excess and does <u>not</u> determine how much product is made.
