A particular chemical reaction is exergonic. What can you say about the relationship between the reactants and the products in t

ozzi

Answer:

Products have a lower total Gibbs free energy in comparison with the reagents total Gibbs free energy.

Explanation:

Hello,

Exergonic chemical reactions are those that the overall Gibbs free energy is negative, it means that the products have a lower total Gibbs free energy, turning out into a spontaneous chemical reaction. Such reactions are thermodynamically possible under standard conditions and they usually release heat.

Best regards.

For the balanced equation shown below, if the reaction of 0.112 grams of

Alekssandra [29.7K]

Answer:

The answer is 74.5%.

Explanation:

As we know that % yield= $\frac{actual yield}{theoretical yield}$ x 100%.

Therefore,

Step 1 Calculate Theoretical yield:

0.112 $H_{2}$ x $\frac{1 mol H_{2} }{2.016 g of H{2} }$ x $\frac{4 mol H_{2}O }{4 mol H_{2} }$ x $\frac{18.02 g H_{2}O }{1 mol H_{2}O}$ = 1.001 g $H_{2}O$

Now Step 2

% yield = $\frac{actual yield}{theoretical yield}$ x 100% = $\frac{0.745g}{1.001g}$ = 74.5%
