Answer:
Half-life at 310 K is 6.54 × 10³ s.
Explanation:
Let's consider the following reaction:
2 N₂O₅(g) → 4 NO₂(g) + O₂(g)
The rate law is:
(Δ[O₂]/Δt) = k . [N₂O₅]
Since [N₂O₅] is raised to the power of 1, the reaction order is 1.
For a first-order reaction:

where,
is the half-life
is the rate constant
At 300 K,

We can use two-point Arrhenius equation to solve for k₂ at 310 K

At 310 K,

It makes the number simpler by putting it up to the next ten ex. 37 will be rounded up to 40
