Answer:

25.)Intrusive rocks have a coarse grained texture. Extrusive Igneous Rocks: ... Quick cooling means that mineral crystals don't have much time to grow, so these rocks have a very fine-grained or even glassy texture. Hot gas bubbles are often trapped in the quenched lava, forming a bubbly, vesicular texture.

Given the following: [G3P] = 1.5x10-5M; [BPG] = 3.0x10-3M ; [NAD+] = 1.2x10-5M; [NADH]=1.0x10-4 ; [HPO42-]= 1.2x10-5 M; pH = 7.5
mel-nik [20]

<u>Answer:</u> The given reaction is non-spontaneous in nature.

<u>Explanation:</u>

To calculate the H^+ concentration, we use the equation:

pH=-\log[H^+]

We are given:

pH of the solution = 7.5

7.5=-\log [H^+]

[H^+]=10^{-7.5)=3.1\times 10^{-8}M

For the given chemical equation:

\text{Glyceraldehyde3-phosphate }+NAD^++HPO_4^{2-}\rightarrow \text{1,3-Biphosphoglycerate }+NADH+H^+

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 = 6.3 kJ/mol = 6300 J/mol  (Conversion factor: 1kJ = 1000J)

R = Gas constant = 8.314J/K mol

T = Temperature = 25^oC=[273+25]K=298K  

K_{eq} = Ratio of concentration of products and reactants = \frac{[BPG][NaDH][H^+]}{[G_3P][NAD^+][HPO_4^{2-}]}

[BPG]=3.0\times 10^{-3}M

[NADH]=1.0\times 10^{-4}M

[H^+]=3.1\times 10^{-8}M

[G_3P]=1.5\times 10^{-5}M

[NAD^+]=1.2\times 10^{-5}M

[HPO_4^{2-}]=1.2\times 10^{-5}M

Putting values in above equation, we get:

\Delta G=6300J/mol+(8.314J/K.mol\times 298K\times \ln (\frac{(3.0\times 10^{-3})\times (1.0\times 10^{-4})\times (3.1\times 10^{-8})}{(1.5\times 10^{-5})\times (1.2\times 10^{-5})\times (1.2\times 10^{-5})}))\\\\\Delta G=9917.02J/mol=9.92kJ/mol

For the reaction to be spontaneous, the Gibbs free energy of the reaction must come out to be negative.

As, the Gibbs free energy of the reaction is positive. The reaction is said to be non-spontaneous.

Hence, the given reaction is non-spontaneous in nature.
