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.

Write the equilibrium expression for N2 (g) + 3 H2 (g) ↔ 2 NH3 (g) + heat I have no idea where to even start, due to the corona
motikmotik

Answer:

The expression of an equilibrium constant will given as:

K_c=\frac{[NH_3]^2}{[N_2][H_2]^3}

Explanation:

Equilibrium constant is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric ratios. It is expressed as K_{eq}

K is the constant of a certain reaction when it is in equilibrium

N_2 (g) + 3 H_2 (g)\rightleftharpoons 2 NH_3 (g) + heat

The expression of an equilibrium constant will given as:

K_c=\frac{[NH_3]^2}{[N_2][H_2]^3}
