Question

Formation of NO2F from NO2 and F2 as per the reaction 2NO2(g) + F2(g) $\longrightarrow$ 2NO2F(g) is a second order reaction, first order with respect to NO2 and first order with respect to F2. If NO2 and F2 are present in a closed vessel in ratio 2 :1 maintained at a constant temperature with an initial total pressure of 3 atm, what will be the total pressure in the vessel after the reaction is complete?

• A. 1atm
• B. 2 atm
• C. 2.5 atm
• D. 3 atm

Answer 1

Answer: (B)

2 atm

Answer 2

$ \text{2N}\text{O}{2}(g)\text{ + }\text{F}{2}(g)\text{ } \rightarrow \text{ 2N}\text{O}_{2}F(g)

}{\text{t = 0} \text{2 atm} \text{1 atm} 0 P_{O}\text{ = 1 atm} }{\text{t = t } 0 0 \text{2 atm}}$$
