zavuch27 [327]

Answer:

When a system is at equilibrium, <u>the process is not spontaneous at either direction.</u>

Explanation:

The process is not spontaneous at either direction , when a system is at equilibrium ΔG = 0, because -

We know that a negative ΔG indicates a forward-moving phase that is random.

We already know that a positive ΔG implies a non-spontaneous phase going forward.

Thus , here ΔG = 0, so the process is not spontaneous in either direction.

Answer: $CaCO_3(s)\rightarrow CaO(s)+CO_2(g)$ , 0.533 L

Explanation:

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

$CaCO_3(s)\rightarrow CaO(s)+CO_2(g)$

According to avogadro's law, 1 mole of every substance occupies 22.4 L of volume at STP.

Number of moles = $\frac{\text {given mass}}{\text {Molar mass}}$

moles of calcium carbonate = $\frac{2.38g}{100g/mol}=0.0238mol$

As 1 mole of calcium carbonate produces = 22.4 L of carbon dioxide at STP

Thus 0.0238 moles of calcium carbonate produces = $\frac{22.4 L}{1}\times 0.0238=0.533L$ of carbon dioxide at STP
