  • Equilibrium Constant K
  • Concentrations - Denoted in [Brackets]
<h3>Step-by-step explanation:</h3>

<u>Step 1: Define</u>

[RxN]   2NO₂ ⇆ N₂O₄

[Equilibrium Rate Law]   \displaystyle K_c = \frac{[N_2O_4]}{[NO_2]^2}

NO₂ = 11.95 M

N₂O₄ = 6.05 M

<u>Step 2: Find K</u>

  1. Substitute [ERL]:                    \displaystyle K_c = \frac{[6.05]}{[11.95]^2}
  2. Exponents:                            \displaystyle K_c = \frac{[6.05]}{[142.803]}
  3. Divide:                                   \displaystyle K_c = 0.042366
  4. Round (Sig Figs):                  \displaystyle K_c \approx 0.0424

This value of K tells us that the reactants are favored in the equilibrium reaction (K < 0.1).

If f(x) is given with points (0,5) and (4,3), it can be easily plotted in a coordinate system (see .jpeg image in attachment).If g(x) is a function defined by text:

Kyle started the summer having read 3 books but plans to read 6 books per month over the summer.Then, g(x) is given with:

g(x) = 6*x+3 (3 books read already, and 6 books will be read each month).h(x) is already given with:

h(x)=3*x+4

These all three functions are plotted in coordinate system and it can be seen that the lowest y-intercept has function g(x), and it is the value of 3 on y-axis. Others have 4 (h(x)) and 5 (f(x)).

-x intercepts: 5, -2
-1/2(x-5)(x+2) is wider than the first equation because the coefficient is smaller
