The mole ratio of ethanol to water : 1 : 3
Further explanation
Given
Reaction
C2H5OH + 302 →2C02 + 3H20
Required
The mole ratio
Solution
In a chemical reaction equation, the mole ratio of the reacting compound (reactants or products) is indicated by the reaction coefficient
The reaction coefficient is determined from the number of elements reacting by holding the principle that the number of elements in the reactants is equal to the number of elements in the product
In the above reaction, the ethanol-C2H5OH coefficient is 1 while the reaction coefficient of water-H20 is 3 so that the mole ratio = 1: 3
