Answer:
to the right (products side)
Explanation:
The equilibrium constant K describes the ratio between the concentration of products and reactants at equilibrium. For a general reaction:
a A + b B → c C + d D
The equilibrium constant expression is:
![K = \frac{[C]^{c} [D]^{d} }{[A]^{a} [B]^{b} }](https://tex.z-dn.net/?f=K%20%3D%20%5Cfrac%7B%5BC%5D%5E%7Bc%7D%20%5BD%5D%5E%7Bd%7D%20%20%7D%7B%5BA%5D%5E%7Ba%7D%20%5BB%5D%5E%7Bb%7D%20%20%7D)
A low value of K indicates that the concentration of products (C and D) is low in relation with the concentration of reactants (A and B).
Conversely, a high value of K indicated that the concentration of products is high compared with the concentration of reactants.
Since K = 6.4 × 10⁹ is a high value, the concentration of products is higher than the concentration of reactants at equilibrium. Thus, the position of the equilibrium is favored to the right.
The system is not at equilibrium.
The reaction will proceed to the right to attain the equilibrium.
Let's consider the following reaction.
2 NOBr(g) ⇌ 2 NO(g) + Br₂(g)
The pressure equilibrium constant (Kp) is 60.6. To determine if the system is at equilibrium when the pressure of each component is 1.75 atm, we have to calculate the reaction quotient (Q) and compare it with Kp.
Q = [NO]².[Br₂] / [NOBr]²
Q = (1.75)².(1.75) / (1.75)²
Q = 1.75
Since Q ≠ Kp, the system is not at equilibrium.
Since Q < Kp, the reaction will proceed to the right to attain the equilibrium.

Answer:
2a. 3mL.
2b. 10mL.
3. 38°C.
Explanation:
2a. We read the volume under the meniscus i.e under the curve.
The volume of the solution is 3mL.
2b. The volume of the pipette 10mL and the solution is at the calibration mark. Therefore, the volume of the solution is 10mL.
3. From the diagram given, we can see that 1 line represents 1 unit.
Now a careful look at the picture shows that the temperature is 38°C.
