Two moles of ideal He gas are contained at a pressure of 1 atm and a temperature of 300 K. 34166 J of heat are transferred to th
iragen [17]

Explanation:

The given data is as follows.

       n = 2 mol,         P = 1 atm,         T = 300 K

        Q = +34166 J,         W= -1216 J (work done against surrounding)

       C_{v} = \frac{3R}{2}

Relation between internal energy, work and heat is as follows.

      Change in internal energy (\Delta U) = Q + W

                                   = [34166 + (-1216)] J

                                   = 32950 J

Also,  \Delta U = n \times C_{v} \times \Delta T

                      = 3R \times (T_{2} - T_{1})

                 32950 J = 3 \times 8.314 J/mol K \times (T_{2} - 300 K)

                \frac{32950}{24.942} = T_{2} - 300 K

                            1321.06 K + 300 K = T_{2}    

                                       T_{2} = 1621.06 K

Thus, we can conclude that the final temperature of the gas is 1621.06 K.

An inhibitor is added to an enzyme-catalyzed reaction at a concentration of 26.7 μM. The Vmax remains constant at 50.0 μM/s, but
fomenos

Using the Michaelis-Menten equation competitive inhibition, the Inhibition constant, Ki of the inhibitor is 53.4 μM.

<h3>What is the Ki for the inhibitor?</h3>

The Ki of an inhibitor is known as the inhibition constant.

The inhibition is a competitive inhibition as the Vmax is unchanged but Km changes.

Using the Michaelis-Menten equation for inhibition:

  • Kma = Km/(1 + [I]/Ki)

Making Ki subject of the formula:

  • Ki = [I]/{(Kma/Km) - 1}

where:

  • Kma is the apparent Km due to inhibitor
  • Km is the Km of the enzyme-catalyzed reaction
  • [I] is the concentration of the inhibitor

Solving for Ki:

where

[I] = 26.7 μM

Km = 1.0

Kma = (150% × 1 ) + 1 = 2.5

Ki = 26.7 μM/{(2.5/1) - 1)

Ki = 53.4 μM

Therefore, the Inhibition constant, Ki of the inhibitor is 53.4 μM.

Phosphorus trichloride, PCl₃ is a liquid at room temperature.
Simora [160]

Answer:

Phosphorus trichloride, PCl₃ undergoes change in bonding and molecular force of attraction, causing it to be liquid at room temperature.

Explanation:

Unlike other chlorides of Period 3 elements, Phosphorus trichloride, PCl₃ changes the structure of its molecular bonding from ionic to covalent bonds as it transitions to fluids (liquids or gases). The PCl₃ molecule also has the weak Van der Waals dispersion and dipole-dipole attraction, making it a fuming liquid at room temperature,  with no electrical conductivity.
