Question
Nitrogen pentoxide decomposes according to equation: $\text{2N}_{2}\text{O}_{5}\text{(g)}\rightarrow\text{4NO}_{2}\text{(g)}+\text{O}_{2}\text{(g)}.$
This first order reactionwas allowed to proceed at $40^\circ C$ and the data below were collected:
This first order reactionwas allowed to proceed at $40^\circ C$ and the data below were collected:
| $[N_2O_5](M)$ | Time (min) |
| $0.400$ | $0.00$ |
| $0.289$ | $20.0$ |
| $0.209$ | $40.0$ |
| $0.151$ | $60.0$ |
| $0.109$ | $80.0$ |
- Calculate the rate constant. Include units with your answer.
- What will be the concentration of $N_2O_5$ after 100 minutes?
- Calculate the initial rate of reaction.
