Answer:
The total pressure would be 8, 93 atm
Explanation:
We apply Dalton's laws, where for a gaseous mixture, the total pressure (Pt) is the sum of the partial pressures (Px) of the gases that make up the mixture.
Pt= Pxa + Pxb+ Pxc....
Pt=2, 20 atm+ 6, 70 atm+ 0,03 atm= 8, 93 atm
Answer: A. inconsistent data
Indeed, using inconsistent data in a research or more to support an argument will only jeopardize its validity. A scientific argument supported by inconsistent data will be considered invalid and unreliable. That's why there are several scientific ways on data gathering.
<u>Answer:</u> The Gibbs free energy of the reaction is 21.32 kJ/mol
<u>Explanation:</u>
The chemical equation follows:
The equation used to Gibbs free energy of the reaction follows:
where,
= free energy of the reaction
= standard Gibbs free energy = 29.7 kJ/mol = 29700 J/mol (Conversion factor: 1 kJ = 1000 J)
R = Gas constant = 8.314J/K mol
T = Temperature = ![37^oC=[273+37]K=310K](https://tex.z-dn.net/?f=37%5EoC%3D%5B273%2B37%5DK%3D310K)
= Ratio of concentration of products and reactants = ![\frac{\text{[Oxaloacetate]}[NADH]}{\text{[Malate]}[NAD^+]}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Ctext%7B%5BOxaloacetate%5D%7D%5BNADH%5D%7D%7B%5Ctext%7B%5BMalate%5D%7D%5BNAD%5E%2B%5D%7D)
![\text{[Oxaloacetate]}=0.130mM](https://tex.z-dn.net/?f=%5Ctext%7B%5BOxaloacetate%5D%7D%3D0.130mM)
![[NADH]=2.0\times 10^2mM](https://tex.z-dn.net/?f=%5BNADH%5D%3D2.0%5Ctimes%2010%5E2mM)
![\text{[Malate]}=1.37mM](https://tex.z-dn.net/?f=%5Ctext%7B%5BMalate%5D%7D%3D1.37mM)
![[NAD^+]=490mM](https://tex.z-dn.net/?f=%5BNAD%5E%2B%5D%3D490mM)
Putting values in above expression, we get:
Hence, the Gibbs free energy of the reaction is 21.32 kJ/mol
The correct option is B. F
