Considering the concept of surface area affecting the rate of reaction, explain why grain storage silos sometimes explode spectacularly?

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.  

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.
