<h3>Answer:</h3>

1270 Psi

<h3>Explanation:</h3>

<u>We are given;</u>

  • Pressure in the tank, P₁ as 422 psi
  • Temperature in the tank, T₁ as 20.0 K
  • New temperature in the tank, T₂ as 60.0 K

We are required to determine the pressure at 60.0 K

  • We are going to use the pressure law;
  • According to the pressure law, the pressure of a gas is directly proportional to  the temperature at constant volume.
  • That is; P\alpha T
  • Thus, \frac{P}{T}=constant
  • At different pressures and temperature;

\frac{P1}{T1} =\frac{P2}{T2}

  • Thus, rearranging the formula;

P2=\frac{P1T2}{T1}

Hence;

P1=\frac{(422Psi)(60K)}{20}

P1=1266Psi

Therefore;

P₂=1266 Psi

   = 1270 Psi

Thus, the pressure at 60.0 K is 1270 Psi

balandron [24]

Answer:

<em>At equilibrium, the rate of the forward, and the reverse reactions are equal.</em>

Explanation:

In an equilibrium chemical reaction, the rate of forward reaction, is equal to the rate of reverse reaction. Note that the reactions does not cease at equilibrium, but rather, the reactants are converted to product, at the same rate at which the product is also being converted into the reactants in the reaction. When chemical equilibrium is reached, a careful calculation of the value of equilibrium constant is approximately equal to 1.

NB: If the value of equilibrium constant is far far greater than 1, then the reaction will favors more of the forward reaction, and if far far less than 1, the reaction will favor more of the reverse reaction.

ki77a [65]

Answer:

Phosphorylation

Explanation:

Phosphorylation is the term used to describe the transfer of a phosphate group (PO34-) from a donor to a receptor molecule or compound. The process of phosphorylation is usually catalysed by a biological enzyme called KINASE.

Phosphorylation can either be addition of an inorganic phosphate to a molecule. For example, addition of phosphate group to ADP to form ATP, or the donation of a phosphate group to another molecule, e.g transfer of phosphate from ATP to glucose to form glucose-6-phosphate during glycolysis.
