Some of the reactants or the products are in the gaseous phase.
A low pressure system has lower pressure at its center than the areas around it. Winds blow towards the low pressure, and the air rises in the atmosphere where they meet.
Radon is a naturally occurring radioactive gas. It comes from radioactive decay of uranium.
It is usually found in igneous rock and soil, but in some cases, well water can also be a source of radon.
<span>The rate of effusion of a gas is inversely proportional to the square root of the molecular weight of the species. Now there will be differences among isotopomers but neglecting these and taking the avg mol wt of N2 = 28 and Xe = 132;
Rate(N2)/Rate(Xe) = sqrt (132/28) = 2.17</span>
