Question
C2H5OH(l)+O2(g) --> CO2(g)+H2O(l), ΔHrxn=−1418 KJ/ mol
How many grams of CO2 were produced if the reaction released 967 kJ of heat?
Expert Solution
Step 1 Heat of reaction
At a particular temperature amount of heat energy released (or) absorbed when a chemical reaction is taking place according to the stoichiometric equation and all the reactants are completely converted in to products is called heat of reaction (ΔHrxn)
Given reaction is
C2H5OH(l) + O2 (g) --> CO2(g) + H2O(l)
balance the reaction
C2H5OH(l) + 3 O2 (g) --> 2 CO2(g) + 3 H2O(l)
Step by step
