What is delta Hrxm dagrees for the following chemical reaction?
CO2(g)+2KOH(s) = H2O(g)+K2CO3(s)
Express your answer in numerically, in kJ
Same answer as your previous post.
delta H rxn = delta H products - delta H reactants.
BOB we just want the damn answer give it to us bro.
To determine the value of ΔHrxn (enthalpy change) for the given chemical reaction, you can use the concept of Hess's law or refer to a source that provides the standard enthalpy of formation (∆H°f) values for the individual compounds involved.
The standard enthalpy of formation is the enthalpy change that occurs when one mole of a compound is formed from its constituent elements in their standard states (at a standard pressure of 1 atm and a standard temperature of 298 K).
To calculate ΔHrxn using standard enthalpy of formation values:
1. Determine the standard enthalpy of formation values for all the compounds involved in the reaction: CO2(g), KOH(s), H2O(g), and K2CO3(s). These values are usually given in tables or can be found online.
2. Write the balanced equation for the reaction and determine the coefficients in front of each compound.
3. Use the equation: ΔHrxn = Σ(∆H°f products) - Σ(∆H°f reactants)
4. Substitute the values of the standard enthalpy of formation for each compound into the equation and calculate ΔHrxn. Be sure to multiply the enthalpy values by the balanced coefficients if necessary.
It is important to note that because ΔH°f values are given in kJ/mol, the resulting ΔHrxn value will also be expressed in kJ.
