How is enthalpy related to the spontaneity of a reaction?

mina [271]

Answer:

Explanation:

Gibb's free energy change(∆G) and Standard electrode potential of electrochemical (Ecell) determine the spontaneity of a reaction.

when ∆G > 0, the reaction is not spontaneous

∆G < 0, the reaction is spontaneous

∆G = 0, the reaction is in equilibrium

when Ecell > 0, the redox reaction is spontaneous

Ecell < 0, the redox reaction is not spontaneous

Ecell = 0, the redox reaction is in equilibrium.

There is about 1.0 g of calcium as Ca2+ in 1.0 L of milk. What is the molarity of Ca2+ in milk?

meriva

Explanation:

It is known that molarity is the number of moles present in a liter of solution.

Molarity = $\frac{\text{no. of moles}}{volume}$

Also, number of moles equal mass divided by molar mass. And, molar mass of calcium is 40.07 g/mol.

No. of moles = $\frac{mass}{\text{molar mass}}$

= $\frac{1.0 g}{40.07 g/mol}$

= 0.025 mol

Therefore, calculate the molarity as follows.

Molarity = $\frac{\text{no. of moles}}{volume}$

= $\frac{0.025 mol}{1.0 L}$

= 0.025 M

Thus, we can conclude that molarity of $Ca^{2+}$ in milk is 0.025 M.
