Consider the following chemical equilibrium: 4NH3+3O2=2N2+6H2O Now write an equation below that shows how to calculate from for

erma4kov [3.2K]

This is an incomplete question, here is a complete question.

Consider the following chemical equilibrium:

$4NH_3(g)+3O_2(g)\rightleftharpoons 2N_2(g)+6H_2O(g)$

Now write an equation below that shows how to calculate Kp from Kc for this reaction at an absolute temperature T. You can assume T is comfortably above room temperature. If you include any common physical constants in your equation be sure you use their standard symbols, found in the ALEKS Calculator.

Answer :

The expression of $K_c$ will be,

$K_c=\frac{[N_2]^2[H_2O]^6}{[NH_3]^4[O_2]^3}$

The expression of $K_p$ will be,

$K_p=K_c(RT)$

Explanation :

Equilibrium constant : It is defined as the equilibrium constant. It is defined as the ratio of concentration of products to the concentration of reactants.

The equilibrium expression for the reaction is determined by multiplying the concentrations of products and divided by the concentrations of the reactants and each concentration is raised to the power that is equal to the coefficient in the balanced reaction.

As we know that the concentrations of pure solids and liquids are constant that is they do not change. Thus, they are not included in the equilibrium expression.

The given equilibrium reaction is,

$4NH_3(g)+3O_2(g)\rightleftharpoons 2N_2(g)+6H_2O(g)$

The expression of $K_c$ will be,

$K_c=\frac{[N_2]^2[H_2O]^6}{[NH_3]^4[O_2]^3}$

The relation between $K_p$ and $K_c$ is:

$K_p=K_c(RT)^{\Delta n}$

Form the above reaction we conclude that:

$\Delta n=n_{product}-n_{reactant}$

$\Delta n=(6+2)-(4+3)$

$\Delta n=1$

The expression of $K_p$ will be,

$K_p=K_c(RT)^{1}$

$K_p=K_c(RT)$

: A ____________ is an arrow that shows the strength and direction of a force.

Sonbull [250]

Answer:

Force arrows are used to represent both the magnitude and direction of forces. The length of the arrow corresponds to the magnitude of the force, with longer arrows indicating forces with larger magnitudes. :) hope this helps

Lridium-192 is an isotope of iridium and has a half-life of 73.83 days. if a laboratory experiment begins with 100 grams of irid

fiasKO [112]

Radioactive material undergoes first order dissociation kinetics.

For 1st order system,
k = 0.693 / t1/2
where, t 1/2 = half-life of the radioactive disintegration process.

Given that, t 1/2 = <span>73.83 days
Therefore, k = 0.009386 day-1

Also, for 1st order reaction,
k = </span> $\frac{2.303}{t} log \frac{Co}{Ct}$

Given that, Co = initial concentration of <span>Iridium-192 = 100 g

Therefore, </span>0.009386 = $\frac{2.303}{t} log \frac{100}{Ct}$

On rearranging we get, Ct = 100 $(0.990656)^{t}$

Answer: Ct = 100 $(0.990656)^{t}$ equation approximates the amount of Iridium-192 present after t days
