Answer:
0.290 atm is the pressure of the system after 7.7min
Explanation:
The general first-order rate constant is:
ln [A] = -kt + ln [A]₀
<em>Where [A] is concentration of A in time t,</em>
<em>K is rate constant, 3.2x10⁻⁴s⁻¹</em>
<em>[A]₀ is initial concentration = 0.336atm.</em>
<em />
7.7 min are:
7.7min * (60s / 1min) = 462s
Solving:
ln [A] = -kt + ln [A]₀
ln [A] = -<em>3.2x10⁻⁴s⁻¹*462s</em> + ln [0.336atm]
ln [A] = -1.238
[A] =
<h3>0.290 atm is the pressure of the system after 7.7min</h3>

The correct answer is resource partitioning.
The concept of resource partitioning is applicable in the branch of ecology. It signifies towards the procedure by which natural selection mediates competing species into distinct patterns of different niches or resource utilization.
When the species differentiate a niche to prevent competition for food resources, it is known as resource partitioning. At certain times, the competition is among the species, known as interspecific competition, and at sometimes it is among the individuals of the similar species, that is, intraspecific competition.
Answer:
b
Explanation:
The reaction that is not a displacement reaction from all the options is 
In a displacement reaction, a part of one of the reactants is replaced by another reactant. In single displacement reactions, one of the reactants completely displaces and replaces part of another reactant. In double displacement reaction, cations and anions in the reactants switch partners to form products.
<em>Options a, c, d, and e involves the displacement of a part of one of the reactants by another reactant while option b does not.</em>
Correct option = b.
