What is the factor that affects how easily an electron can be removed from an atom?

1 answer:

8 0

I think the correct answer among the choices listed above is option D. It is the structure of the atom that is the <span>factor that affects how easily an electron can be removed from an atom. This is because having a stronger structure would mean that electrons have a strong attraction to the atom and it would be harder to remove the electrons.</span>

Consider the malate dehydrogenase reaction from the citric acid cycle. Given the listed concentrations, calculate the free energ

Ahat [919]

<u>Answer:</u> The Gibbs free energy of the reaction is 21.32 kJ/mol

<u>Explanation:</u>

The chemical equation follows:

$\text{Malate }+NAD^+\rightleftharpoons \text{Oxaloacetate }+NADH$

The equation used to Gibbs free energy of the reaction follows:

$\Delta G=\Delta G^o+RT\ln K_{eq}$

where,

$\Delta G$ = free energy of the reaction

$\Delta G^o$ = 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 = $37^oC=[273+37]K=310K$

$K_{eq}$ = Ratio of concentration of products and reactants = $\frac{\text{[Oxaloacetate]}[NADH]}{\text{[Malate]}[NAD^+]}$

$\text{[Oxaloacetate]}=0.130mM$

$[NADH]=2.0\times 10^2mM$

$\text{[Malate]}=1.37mM$

$[NAD^+]=490mM$

Putting values in above expression, we get:

$\Delta G=29700J/mol+(8.314J/K.mol\times 310K\times \ln (\frac{0.130\times 2.0\times 10^2}{1.37\times 490}))\\\\\Delta G=21320.7J/mol=21.32kJ/mol$

Hence, the Gibbs free energy of the reaction is 21.32 kJ/mol

What information does the rate constant give from the rate law? A. It tells how much the rate of the reaction is affected by vol

Levart [38]

From the rate law, the information that is given by the rate constant is: C. It tells how much the reaction rate is affected by activation energy.

Rate law is also referred to as rate equation and it can be defined as a chemical equation that is typically used to relate the initial (forward) chemical reaction rate with respect to the concentrations or pressures of the chemical reactants and constant parameters.

Mathematically, the rate law is given by this formula:

$R = k[A]^x[B]^y$

<u>Where:</u>

k is the rate constant.

A is the concentration of reactant A.

B is the concentration of reactant B.

In Chemistry, the rate constant is typically used to tell the reaction rate or rate of a chemical reaction that is affected by activation energy.

The addition of a catalyst in a chemical reaction

malfutka [58]

The addition of catalyst in a chemical reaction has 2 functions
1. if you add negative catalyst then the rate of chemical reaction decreases
2. if you add positive catalyst then the rate of chemical reaction increases.
