Answer:

9 × 10⁻³ mol·L⁻¹s⁻¹  

Explanation:

Data:

  k = 1 × 10⁻³ L·mol⁻¹s⁻¹

[A] = 3 mol·L⁻¹

Calculation:

rate = k[A]² = 1 × 10⁻³ L·mol⁻¹s⁻¹ × (3 mol·L⁻¹)² = 9 × 10⁻³ mol·L⁻¹s⁻¹

Answer:

(1) The two column proof is presented here as follows;

Statement         {}                                Reasons

1. C is the midpoint of \overline {AE}         {}           Given  

  B is the midpoint of \overline {AC}         {}          

  D is the midpoint of \overline {CE}         {}          

2. AC = CE, AB = BC, CD = DE        {}      Definition of midpoint

3. AB + BC = AC, CD + DE = CE      {}       Segment addition postulate

4. CD + DE = AC        {}                             Substitution property of equality

5. AB + BC = CD + DE  {}                          Substitution property of equality

6. BC + BC = CD + CD          {}                  Substitution property of equality

7. 2·BC = 2·CD         {}                               Addition of two identical quantities

8. BC = CD  {}                                            Division property of equality

9. BC ≅  CD     {}                                       Definition of Congruence

(2) The two column proof for the triangular geometric figure is presented here as follows;

Statement         {}                                        Reasons

1. 2·WV = XY; 2·YZ = XW; WV = YZ   {}      Given

2.  2·WV = 2·YZ        {}                                Multiplication property

3. XY = XW        {}                                       Substitution Property

4. XW + WV = XV       {}                              Segment Addition Property

XY + YZ = XZ

5. XW + WV = XV      {}                              Substitution Property

XW + WV = XZ

6. XV = XZ       {}                                        Substitution Property
