# Calculating N2O4 Reaction Rate in 4L Container

• Nanu Nana
In summary, the process involves the conversion of 3/4 of 0.20 mole of N2O4 in a 4.0L container. Using the equation c=mole/L, the concentration of N2O4 is calculated to be 0.05 M. The reaction rate is then determined by multiplying the concentration by the given rate constant (k=0.050 s-1), resulting in a value of 0.001875. However, the correct answer for the reaction rate is 6.3x10^-4, leaving the question of how much N2O4 is left after 3/4 is converted unanswered.

## Homework Statement

N2O4 --------------> NO2 N2O4 for k = 0.050 s-1
The process starts from 0.20 mole of N2O4 in a container of 4.0L. Calculate v for N2O4.
if 3/4 of the N2O4 is converted

## Homework Equations

To calculate concentration
c= mole/L

## The Attempt at a Solution

0.20 mole /4.0 L =0.05 M
(3/4)x0.05 =0.0375 M
V(reaction rate) = k .0.0375M
v= 0.050 s-1 x 0.0375 M
v=0.001875
But the answer should be 6.3x10^-4 [/B]

That's a given.

## 1. What is the formula for calculating the reaction rate of N2O4 in a 4L container?

The formula for calculating the reaction rate of N2O4 in a 4L container is: rate = -Δ[N2O4]/Δt, where Δ[N2O4] is the change in concentration of N2O4 over time and Δt is the change in time.

## 2. How do you determine the initial concentration of N2O4 in the 4L container?

To determine the initial concentration of N2O4, you will need to know the molar mass of N2O4 and the number of moles present in the 4L container. Then, divide the number of moles by the volume (4L) to find the initial concentration in mol/L.

## 3. Can the reaction rate of N2O4 in a 4L container be affected by temperature?

Yes, the reaction rate of N2O4 in a 4L container can be affected by temperature. Generally, an increase in temperature will result in a higher reaction rate due to the increased kinetic energy of the molecules.

## 4. What units are typically used to express the reaction rate of N2O4 in a 4L container?

The reaction rate of N2O4 in a 4L container is typically expressed in units of mol/L*s (moles per liter per second).

## 5. How can the reaction rate of N2O4 in a 4L container be altered or controlled?

The reaction rate of N2O4 in a 4L container can be altered or controlled by changing the initial concentration of N2O4, adjusting the temperature, or adding a catalyst to the reaction. Other factors such as pressure and surface area may also have an effect on the reaction rate.
