Answer:

Explanation:

Relation between ΔG₀ and K ( equilibrium constant ) is as follows .

lnK =  -  ΔG₀ / RT

K = e^{-\frac{\triangle G_0}{RT}

The value of R and T are same for all reactions .

So higher the value of negative ΔG₀ , higher will be the value of K  .

Mg(s) + N₂0(g) → MgO(s) + N₂(g)

has the ΔG₀ value of -673 kJ which is highest negative value . So this reaction will have highest value of equilibrium constant K .

Explanation:

To balance the reactions given, we must understand that the principle to follow is the law of conservation of matter.

Based on this premise, the number of moles of species on the reactant and product side must be the same;

 

      Li   +   Br₂  →    LiBr

Put a,b and c as the coefficient of each species

   aLi  + bBr₂ → cLiBr

balancing Li;

       a  = c

 balancing Br;

        2b  = c

 let a  = 1;

       c  = 1

        b = \frac{1}{2}  

or a = 2, b = 1 , c = 2

        2Li   +   Br₂  →    2LiBr

        P   +   Cl₂  →    PCl₃

Using the same method;

      aP  + bCl₂ → cPCl₃

balancing P;

          a  = c

balancing Cl;

          2b  = 3c

let a = 1;

     c  = 1

      b  = \frac{3}{2}

 or

  a  = 2, b  = 3, c  = 2

    2P   +   3Cl₂  →    2PCl₃

iii,

   H₂   +   SO₂  →   H₂S   +   H₂O

use coefficients a,b,c and d;

    aH₂   +   bSO₂  →   cH₂S   +   dH₂O

balancing H;

    2a = 2c + 2d

balancing S;

     b  = c

balancing O

    2b  = d

 let b  = 1,

      c = 1

       d  = 2

    a  = 3

    3H₂   +   SO₂  →   H₂S   +   2H₂O

Exam 3 Material

Homework Page Without Visible Answers

This page has all of the required homework for the material covered in the third exam of the first semester of General Chemistry. The textbook associated with this homework is CHEMISTRY The Central Science by Brown, LeMay, et.al. The last edition I required students to buy was the 12th edition (CHEMISTRY The Central Science, 12th ed. by Brown, LeMay, Bursten, Murphy and Woodward), but any edition of this text will do for this course.

Note: You are expected to go to the end of chapter problems in your textbook, find similar questions, and work out those problems as well. This is just the required list of problems for quiz purposes. You should also study the Exercises within the chapters. The exercises are worked out examples of the questions at the back of the chapter. The study guide also has worked out examples.

These are bare-bones questions. The textbook questions will have additional information that may be useful and that connects the problems to real life applications, many of them in biology.
