Question

Which statement about the change in bond energy of this reaction is correct?(1 point)

Answer 1

`\begin{gathered} Enthalpy\text{ }change=sum\text{ }bonds\text{ }broken-sum\text{ }bondsformed \\ \Delta H=2612kJmol^(-1)-3016kJmol^(-1) \\ \Delta H=-404kJmol^(-1) \end{gathered}`

Reaction is therefore exothermic because the bonds in the products are greater than that of the reactants.
