### What is the equilibrium constant for N2O4?

The equilibrium constants for the reaction N2O4 (g)=2NO2 (g), at the temperatures 299.71°, 303.70°, and 308.89°K, have been evaluated by combining precise transmittance measurements for the 5461‐Å mercury line with the known vapor pressures of solid N2O4.

What is the equilibrium constant of KP?

Equilibrium constant expression in terms of partial pressure is designated as Kp. Equilibrium constant Kp is equal to the partial pressure of products divided by partial pressure of reactants and the partial pressure are raised with some power which is equal to the coefficient of the substance in balanced equation.

What is KC for 2NO2 N2O4?

Kc for the equilibrium N2O4 (g) 2NO2(g) at 298^0C is 5.7 × 10^-9 .

## What is KP at 400 K for the reaction 2NO2 g ⇌ N2O4 g )?

For the reaction N2O4(g)⇌2NO2(g), the value of K is 50 at 400 K and 1700 at 500 K.

### What is unit of KP for the reaction N2O4 g 2NO2 g?

The equilibrium constant Kp for the reaction N2O4(g) 2NO2(g) is 4.5 .

What is KP at 300 K for the reaction 2NO2 g ⇌ N2O4 g )?

At 300 K, Kp for the gaseous reaction N2O4(g) 2NO2(g) is 6.7 .

Is KC equal to KP?

∆n = moles of gaseous products œ moles of gaseous reactants ⇒ Note that Kc = Kp when the number of gas molecules are the same on both sides.

## What is KP and KC in equilibrium?

Kp And Kc are the equilibrium constant of an ideal gaseous mixture. Kp is equilibrium constant used when equilibrium concentrations are expressed in atmospheric pressure and Kc is equilibrium constant used when equilibrium concentrations are expressed in molarity. For many general chemical reactions aA + bB ⇋ cC + dD.

### Does KP equal KC at equilibrium?

Kp only counts with gases molecule , while Kc only counts with aqueous solution+ gases. So here reactant and product both are gaseous that’s why only reaction having equal numbers of reactants and products will have kp=kc ie.

How do you calculate KP and KC?

So if you want to get to Kp from Kc, the equation is this. So you have Kp equals Kc times RT to the delta n. Kp is the equilibrium constant and pressures. So using our example, Kp would have been equal to the pressure of NO2 gas, and that quantity squared,over the pressure of N2O4 gas.

How do you find KP when given KC?

The general expression: Kp = Kc(RT) ∆n can be derived where ∆n = moles of gaseous products – moles of gaseous reactants.

## What is the equilibrium constant for the reaction N2O4 2NO2?

The equilibrium constant Kp for the reaction N2O4 (g) 2NO2 (g) is 4.5 . What would be the average molar mass (in g/mol) of an equilibrium mixture of N2O4 and NO2 formed by the dissociation of pure N2O4 at a total pressure of 2 atm? The Fish Tale Across the Wall Tenths and HundredthsParts and Whole Can you see the Pattern?

### What is the kJ value of N2O4 G?

N2O4(g) <–> 2 NO2(g) ∆H = 58.0 kJ A computer animation representing what occurs at the particulate level was available but it is missing. The computer animation needs to be re-built.

What happens when you mix NO2 and N2O4?

Heating or cooling flasks of NO2 and N2O4 shifts the equilibrium between these two species. When more NO2 is produced, the color of the gas inside the flask becomes darker brown. N2O4(g) <–> 2 NO2(g) ∆H = 58.0 kJ

What happens at the particulate level when more NO2 produced?

When more NO2 is produced, the color of the gas inside the flask becomes darker brown. N2O4(g) <–> 2 NO2(g) ∆H = 58.0 kJ A computer animation representing what occurs at the particulate level was available but it is missing. The computer animation needs to be re-built.
