Consider the reaction, `aX_(2)(g)+bY_(2)(g)hArrcXY(g)+` heat and answer the following questions:
Find the relation among a,b and c.

Explanation

According to the equation of the reaction, c mol of XY forms when a mol of `X_(2)` reacts with b mol of `Y_(2)`.
So, the number of X atoms in a mol of `X_(2)`=The number of X atoms in c mol of XY.
`therefore 2xxa=c or, a=(c)/(2)`.
Similarly, the number of Y atoms in b mol of `Y_(2)`=the number of Y atoms in c mol of XY.
`therefore 2xxb=c or, b=(c)/(2)`. Therefore, `a=b=(c)/(2)`.
