Which of the following statement regarding energy flow are accurate?

a. If the reactants have higher internal energy than the products, ΔE sys is positive and energy flows out the system into the surroundings.

b.If the reactants have lower internal energy than the products, ΔE sys is positive and energy flows out the system into the surroundings.

c.If the reactants have higher internal energy than the products, ΔE sys is negative and energy flows out the system into the surroundings.

d.If the reactants have lower internal energy than the products, ΔE sys is negative and energy flows out the system into the surroundings.

Which of the following statement regarding energy flow are accurate?

a. If the reactants have higher internal energy than the products, ΔE sys is positive and energy flows out the system into the surroundings.

dE = Eproducts - Ereactants

Eprod < Ereact; then this is going to be NEGATIVE, meaning that the system loses energy, that is, it releases energy to the surroundings,

dE system = negative; this is then false

b.If the reactants have lower internal energy than the products, ΔE sys is positive and energy flows out the system into the surroundings.

dE = Eproducts - Ereactants

Eprod < Ereact; then this is going to be NEGATIVE, meaning that the system loses energy, that is, it releases energy to the surroundings,

dE system = negative; this is then false

c.If the reactants have higher internal energy than the products, ΔE sys is negative and energy flows out the system into the surroundings.

dE = Eproducts - Ereactants

Eprod < Ereact; then this is going to be NEGATIVE, meaning that the system loses energy, that is, it releases energy to the surroundings,

dE system = negative; this is then TRUE

d.If the reactants have lower internal energy than the products, ΔE sys is negative and energy flows out the system into the surroundings

dE = Eproducts - Ereactants

Eprod < Ereact; then this is going to be NEGATIVE, meaning that the system loses energy, that is, it releases energy to the surroundings,

dE system = negative; this is then false
