Question

For the reaction shown in the diagram, what is the uncatalyzed activation energy?

• A. $A$
• B. $B$
• C. $C$
• D. $B-C$
• E. $A-C$

Answer 1

The correct option is B $B$

$A⟶$ Show the catalyses activation energy which is due to addition of catalyst.

$B⟶$ Show the uncatalogued activation energy which is due to absence of catalyst.

$C⟶$ It show the enthalpy of product

$D⟶$ It show the change in enthalpy of reaction i.e. $\Delta H_{reaction}=\Delta H_{product}-\Delta H_{reactant}$
