Answer:
Option C. 251 kJ
Explanation:
The activation energy (Ea) of a given reaction is the minimum energy that must be overcomed for reactant to proceed to product.
The activation energy (Ea) can be obtained from an energy profile diagram by simply calculating the difference between the energy of the activation complex (i.e the peak) and the energy of the reactant.
Thus, we can obtain the activation energy for the reaction above as follow:
Activation complex = 332.6 kJ
Energy of reactant = 81.6 kJ
Activation energy =?
Activation energy = Activation complex – Energy of reactant
Activation energy = 332.6 – 81.6
Activation energy = 251 kJ
Therefore, the activation energy of the reaction is 251 kJ
3. The Chemical property of an unknown element is the number of valence electrons
4. The number of protons in one atom of an element
Hope I helped :))
Efficiency of the ram is calculated by dividing the work done by the work or energy that is exerted to do so. This is calculated through the equation,
S = ((Wout) / (Win)) x 100%
Substiuting the known values to the equation.
S = (153 J)/(185 J) x 100%
Efficiency = 82.7%.
