<span>The rate of substance B
being consumed should be equal to that of the substance A. Dynamic equilibrium
is the balance in a process that is continuing. It is achieved in a reaction
when the forward rate of reaction and the backward rate of reaction is at the
same value or equal.</span>

Answer:
Half-life at 310 K is 6.54 × 10³ s.
Explanation:
Let's consider the following reaction:
2 N₂O₅(g) → 4 NO₂(g) + O₂(g)
The rate law is:
(Δ[O₂]/Δt) = k . [N₂O₅]
Since [N₂O₅] is raised to the power of 1, the reaction order is 1.
For a first-order reaction:

where,
is the half-life
is the rate constant
At 300 K,

We can use two-point Arrhenius equation to solve for k₂ at 310 K

At 310 K,

Answer:
The Human body will react in lots of different ways, look down below

- Bone mass decreases
- The Body grows slightly taller
That's all I know at the moment. Hope I could help!
Answer:

Explanation:
Hello!
In this case, since pyridinium chloride has a pKb of 8.77 which is a Kb of 1.70x10⁻⁹ and therefore a Ka of 5.89x10⁻⁵ which means it tends to be acidic, we write its ionization via:

Because it is a Bronsted base which donates one hydrogen ion to the water to produce hydronium. Thus, we write the equilibrium expression with the aqueous species only:
![Ka=\frac{[C_5H_5NCl^-][H_3O^+]}{[C_5H_5NHCl]}](https://tex.z-dn.net/?f=Ka%3D%5Cfrac%7B%5BC_5H_5NCl%5E-%5D%5BH_3O%5E%2B%5D%7D%7B%5BC_5H_5NHCl%5D%7D)
In terms of the reaction extent
, we write:

Thus, solving for
we obtain:

Clearly the solution is 0.0048 M because to negative values are not allowed, therefore, since it equals the concentration of hydronium which defines the pH, we write:
![pH=-log([H_3O^+])=-log(0.0048)\\\\pH=2.3](https://tex.z-dn.net/?f=pH%3D-log%28%5BH_3O%5E%2B%5D%29%3D-log%280.0048%29%5C%5C%5C%5CpH%3D2.3)
