In order of increasing energy,
2s < 3p < 4s < 3d
Answer:
The smaller a particles the higher the surface area to volume ratio
Explanation:
In a grain silo, there are lots of minute dust grain particles and chaff floating in the air. The silo is important in keeping the grains dry hence there is little moisture. These particles, when concentrated, are therefore highly combustible and the slightest spartk can cause a spectacular explosion.
We can dictate the mechanism of the reaction by looking at the exponents of the reactants in the reaction rate equation. Since [xy] has an exponent of 1, then the reaction follows the first order reaction with respect to xy. Similarly, the reaction follows the first order with respect to z₂. Then, the overall is the sum of each of their orders which is 2.
