Question

Consider the energy diagram, Find ΔE forward.Answer in units of kJ/mol

Answer 1

`\Delta E_(forward)\text{ =-31KJ}`

Step-by-step explanation

Given that;

The energy on the product side = -40KJ

The energy on the reactant side = - 9KJ

To find the change in energy, follow the steps below

From the energy diagram provided, The energy level on the product side is higher than the energy level on the reactant side

Step 1: Write the change in energy formula

`\begin{gathered} \Delta E\text{ = }\Delta E_(PRODUCT)\text{ - }\Delta E_(REACTANT) \\ \end{gathered}`

Step 2: Substitute the given data into the above formula

`\begin{gathered} \Delta E\text{ = -40 - \lparen-9\rparen} \\ \Delta E\text{ = -40 + 9} \\ \text{ }\Delta E\text{ = -31KJ} \end{gathered}`
