QAIPMT-2010-Ch-1994: NEET 2010 Chemistry - Class 11 AIPMT-2010-Ch-1994 Solution: For an endothermic reaction, energy of activation is \(E_a\)…

For an endothermic reaction, energy of activation is EaE_a and enthalpy of reaction is ΔH\Delta H (both of these in kJ/mol). Minimum value of EaE_a will be

Multiple Choice Options

  • A less than ΔH\Delta H
  • B equal to ΔH\Delta H
  • C more than ΔH\Delta H
  • D equal to zero

Step-by-Step Verified Solution

Here, E a = activation energy of forward reaction E� a = activation energy of backward reaction _ H = enthalpy of the reaction From the given diagram it is clear that E a = E� a + _ H _ E a > _ H
