The decomposition of dinitrogen pentoxide (N2O5) follows first order rate law. What will be the rate constant from the given data?
At t = 800 s, [N2O5] = 1.45 mol L–1
At t = 1600 s, [N2O5] = 0.88 mol L–1
At t = 800 s, [N2O5] = 1.45 mol L–1
At t = 1600 s, [N2O5] = 0.88 mol L–1
- 3.12 × 10–4 s–1
- 6.24 × 10–4 s–1
- 2.84 × 10–4 s–1
- 8.14 × 10–4 s–1
Answer
(B) 6.24 × 10 –4 s –1
