Answer: The percentage error is 16.6 %.
Explanation:
To calculate the percentage error, we use the equation:
[tex]\%\text{ error}=\frac{|\text{Experimental value - Accepted value}|}{\text{Accepted value}}\times 100[/tex]
We are given:
Experimental value of ΔH = -43.1 kJ/mol
Accepted value of ΔH = -51.669 kJ/mol
Putting values in above equation, we get:
[tex]\%\text{ error}=\frac{|(-43.1)-(-51.669)|}{(51.669)}\times 100\\\\\%\text{ error}=16.6\%[/tex]
Hence, the percentage error is 16.6 %.
