Answer:

Avogadro's Law; 15.1L

Explanation:

Boyle's Law- Pressure and volume are <u>inversely</u> related, so an increase in pressure= decrease in volume. We see this in the equation P1V1=P2V2.

Charle's Law- Gas expands/increases in volume when temperature increases, so they are <u>proportional</u>. We see this in the formula \frac{V1}{T1} = \frac{V2}{T2}.

Guy-Lussac's Law-  As temperature increases, pressure increases, so they are <u>proportional</u>. We see this in the formula \frac{P1}{T1} = \frac{P2}{T2}.

Avogadro's Law- There are equal amount of volume have an equal amount of moles, so they are proportional. We see this in the formula \frac{V1}{n1} = \frac{V2}{n2}.

Plugging in the values based on Avogadro's Law, we'll have:

\frac{36.5}{2.9} = \frac{V2}{1.2}

12.6 = \frac{V2}{1.2}

12.6 x 1.2 = V2

15.1L =V2

What is ΔG for the reaction at body temperature (37.0 °C) if the concentration of A is 1.6 M and the concentration of B is 0.50
Galina-37 [17]

Answer:

The Gibbs free energy is -2997.83 kJ mol-1.

Explanation:

The change in Gibbs free energy of the reaction \Delta G can be calculated using the formula.

\Delta G = -RTlnK

WHere R = Gas constant = 8.314KJ/Kmol

T = the temperature of the reaction in Kelvin = (37.0 + 273) = 310K

K = Raio of molar concentration of the two reactants = 1.6/0.5 = 3.2

Therefore,

\Delta G = -8.314 \times 310 \times  ln (3.2) = -2997.83 kJ mol-1

Therefore the Gibbs free energy is -2997.83 kJ mol-1.

The negative sign indicates that the reaction is spontaneous.
