the reaction a(g) ⇌ b(g) has an equilibrium constant that is less than one. what can you conclude about ∆g° for the reaction?
-Dominant- [34]

For this reaction: ΔG⁰>0.

Balanced chemical reaction A(g) ⇌ (g)

ΔG° indicates that all reactants and products are in their standard states.

ΔG° = R·T·lnK.

ΔG° is Gibbs free energy

T is the temperature on the Kelvin scale

R is the ideal gas constant

The equilibrium constant (K) is the ratio of the partial pressures or the concentrations of products to reactants.

Gibbs free energy (G) determines if reaction will proceed spontaneously, nonspontaneously or in equilibrium processes.

If K < 1, than ΔG° > 0.

Reactants (in this example A) are favored over products (in this example B) at equilibrium.

At what temperature does a gas at 1.00 atm and 20 degree Celsius have a pressure of 4.00 atm.
vfiekz [6]

Answer:

P1 =4 atm

T1= 20°C

P2=1 atm

T2=?

According to Gay-Lussac's Law or Third Gas Law,

P1T2=P2T1

4×T2=1×20

T2= 20/4

T2= 5°C

Answer At 5°C temperature does a gas at 1.00 atm !

Ability to conduct electricity
Alex17521 [72]

Metals have the ability to conduct electricity.

Metals are lustrous, malleable, ductile and are good conductor of heat and electricity.

They conduct electricity because the electrons in metal are delocalized electrons and are free moving electrons so when they gain energy (heat) they vibrate more quickly and can move around, this means that they can pass on the energy more quickly.

Boyle's law states that gas volume is Boyle's law states that gas volume is inversely proportional to temperature. directly prop
ankoles [38]

<u>Answer:</u> Boyle's law states that gas volume is inversely proportional to pressure.

<u>Explanation:</u>

Boyle's law is one of the law used to determine the Ideal Gas equation.

This law states that pressure of the gas is inversely proportional to the volume of the gas at constant temperature and number of moles

Mathematically,

P\propto \frac{1}{V}          (at constant temperature and number of moles)

The above expression can also be written as:

P_1V_1=P_2V_2

where,

P_1\text{ and }V_1 are initial pressure and volume of the gas

P_2\text{ and }V_2 are final pressure and volume of the gas

Hence, Boyle's law states that gas volume is inversely proportional to pressure.
