Mention atleast three ways by which the concentration of `SO_(2)(g)` be increased in the following reaction in a state of equilibrium :
`2SO_(2) (g) + O_(2) (g) hArr 2SO_(3) (g) +` heat.

Explanation

To increase the concentration of \( SO_2(g) \) in the equilibrium reaction:

\[ 2SO_2(g) + O_2(g) \rightleftharpoons 2SO_3(g) + \text{heat} \]

we can apply Le Chatelier's principle, which states that if a dynamic equilibrium is disturbed by changing the conditions, the position of equilibrium shifts to counteract the change. Here are three ways to achieve this:
