Question

Consider the given plot of enthalpy of the following reaction between A and B. A + B → C + D Identify the incorrect statement. (A) C is the thermodynamically stable product. (B) Formation of A and B from C has highest enthalpy of activation. (C) D is kinetically stable product. (D) Activation enthalpy to form C is 5kJ mol-1 less than that to form D.

A + B → C + D Activation enthalpy for C = 20 - 5 = 15 kJ/mol Activation enthalpy for D = 15 - 5 = 10 kJ/mol

Q. Consider the given plot of enthalpy of the following reaction between $A$ and $B$ .
$A + B \to C + D$
Identify the incorrect statement.

C is the thermodynamically stable product.

Formation of A and B from C has highest enthalpy of activation.

D is kinetically stable product.

Activation enthalpy to form C is $5 k J m o l^{- 1}$ less than that to form D.

A + B $\to$ C + D
Activation enthalpy for $C = 20 - 5 = 15 k J / m o l$
Activation enthalpy for $D = 15 - 5 = 10 k J / m o l$

Q. Consider the given plot of enthalpy of the following reaction between A and B. A+B→C+D Identify the incorrect statement.
