What volume of nitric dioxied at s.t.p from the below equestion N2+O2=2NO
5.32
How much O2 and N2 are you starting with?
To determine the volume of nitric dioxide (NO2) at standard temperature and pressure (STP) from the equation N2 + O2 = 2NO, we need to follow these steps:
1. Convert the chemical equation to a balanced equation if needed:
N2 + O2 → 2NO
2. Use the balanced equation to find the molar ratio between nitrogen dioxide (NO2) and nitrogen monoxide (NO):
In the equation, the molar ratio between NO and NO2 is 2:2 or 1:1.
3. Determine the number of moles of nitrogen dioxide (NO2) produced:
Since the molar ratio between NO and NO2 is 1:1, the number of moles of NO2 will be the same as the number of moles of NO.
4. Use the ideal gas law to calculate the volume of nitrogen dioxide at STP:
The ideal gas law equation is PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the ideal gas constant (0.0821 L·atm/(mol·K)), and T is the temperature in Kelvin.
At STP, the temperature (T) is 273.15 Kelvin, and the pressure (P) is 1 atmosphere.
Therefore, we can rearrange the ideal gas law equation to solve for volume (V):
V = (nRT)/P
5. Plug in the values into the equation:
- Substitute the number of moles (from step 3), the ideal gas constant (R = 0.0821 L·atm/(mol·K)), the temperature at STP (T = 273.15 K), and the pressure at STP (P = 1 atm) into the equation.
6. Calculate the volume:
Plug the values into the equation and calculate the volume of nitrogen dioxide at STP.
Please provide the moles of nitrogen monoxide (NO) produced, and I can help you further calculate the volume of nitrogen dioxide (NO2) at STP.
