CO + 2H2 ⇌ CH3OH ΔH <0

1 answer:

sveta [45]3 years ago

5 0

Answer:

C. The energy released as the bonds in the reactants are broken is greater than the energy absorbed as the bonds in the product are formed.

Explanation:

CO + 2H₂ ⇌ CH₃OH ΔH <0

As ΔH is negative, the given reaction is exothermic.

That means that <em>the enthalpy of the product is less than the enthalpy of the reactants</em>. In other words, part of the energy from the reactants is used to form new bonds (between C and H, for example), while the other part is transfered outside the system as heat.

Thus the correct answer is C.

A chemist fills a reaction vessel with 9.47 atm nitrogen monoxide (NO) gas, 2.61 atm chlorine (C12) gas, and 8.64 atm nitrosyl c

lys-0071 [83]

Answer:

$\Delta _rG=2832.2J/mol$

Explanation:

Hello,

In this case, the Gibbs free energy of that reaction is computed by computing the equilibrium constant as:

$K=\frac{p_{NOCl}^2}{p_{NO}^2p_{Cl_2}} =\frac{8.64^2}{9.47^2*2.61}=0.319$

Hence the Gibbs free energy:

$\Delta _rG=-RTlog(K)=-8.314\frac{J}{mol*K}*298.15K*ln(0.319)\\\\\Delta _rG=2832.2J/mol$

Best regards.

What is a physical change

Shtirlitz [24]

Answer:

A physical change is a change that does not change the chemical properties of the substance and is purely physical.

Explanation:

The appearance of the object of chemical may change but its chemical properties are the same.

For example:

Ice melting
Water boiling
Dissolving salt in water
Cutting paper
