For a particular reaction, the change in enthalpy is 51kjmole and the activation energy is 109kjmole. which of the following could not be the change in enthalpy (δh) and the activation energy (ea), respectively, for the catalyzed reaction? select all that apply.

Answer

given,

change in enthalpy = 51 kJ/mole

change in activation energy = 109 kJ/mole

when a reaction is catalysed change in enthalpy between the product and the reactant does not change it remain constant.

where as activation energy of the product and the reactant decreases.

example:

ΔH = 51 kJ/mole

E_a= 83 kJ/mole

here activation energy decrease whereas change in enthalpy remains same.

no image, but probably absorption

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees.
