`2x + 3y rarrt 41 + m`
(i) 2x reacts with 3y to give products.
8x reacts with 15y means, y is the excess because 8 moles ofx should react with 4 `xx` 3y = I2y moles of y to give products.
In this reaction 15y moles are used.
Therefore, 3 moles of y is excess and x is the limiting agent.
(ii) When 8 moles of x react with 12 moles of y, the product formed will be 4 `xx` 41 i.e. 161 and 4m as product.
8x + 12y `rarr` 161 + 4m
(iii) At the end of the reaction, the excess reactant left is 3 moles of y
