Question

Consider a reaction in which hydrogen (H2) and oxygen (O2) react to form water (H2O). By mass, the mixture of reactants is 1 part hydrogen and 6 parts oxygen. Write the chemical reaction showing reactant and products including any leftover oxygen or hydrogen. Calculate the equivalence ratio for this reaction.

Answer 1

Answer:

equivalence ratio= 0.08333

Explanation:

The balanced stoichoimetric equation tells us the amount of hydrogen in moles required to react with a specific amount of oxygen in moles to produce water. The Balanced equation of the reaction is shown

2H_{2}+O_{2}  → 2 H_{2}O

this means 2 parts of Hydrogen will react with one part of oxgen to produce 2parts of water as shown above

in the question, 1 part of hydrogen was made to react with 6parts of oxygen. which means comparing with the balanced equation, oxygen is in excess as only \frac{1}{2} part of oxygen will react with 1part of hydrogen. the equation is shown below

1H_{2}+\frac{1}{2} O_{2}  → 1 H_{2}O +\frac{11}{2}O_{2}  

The equivalence ratio is the ratio of actual fuel to air ratio to stoichiometric fuel to air ratio and is calculated as follows:

actual fuel/air ratio = parts of fuel/parts of air

                               =\frac{1}{6}

stoichiometric fuel/air ratio = \frac{2}{1}

equivalence ratio = \frac{actual fuel/air ratio}{stoichiometric fuel/air ratio }

                             =\frac{\frac{1}{6} }{\frac{2}{1} }

                             = 0.08333
