Answer:
Five ( 5 ) is the correct answer
Answer: 151 kJ
Explanation:
To calculate the moles :
It is given that:
0.267 moles of 
absorb energy = 40.3 kJ
Thus 1 mole of absorb energy =
Thus the value of 
for the chemical equation given is 151 kJ
Answer:
The rate of reaction rA is an intensive parameter.
Explanation:
The rate of reaction for a chemical species is typically -rA. Negative sign only shows that reactants are consumed when time is passing in the reaction.
Reaction rate will depend of several factors such as: Constant of equilibrium - K, Concentration of species - CA, Temperature - T and so on.
When we analyze the reaction rate the units are mol/Ls. It means that reaction rate will only depend of concentration and other variables. In this way, rate of reaction only is afected when we have changes in concentrations.
Concentration is an intensive parameter, it is not important if we have 100 kg or 100 L, or even 1 Kg or 1 L of total solution. Concentrations are the proportion of them and they will remain constant independent of the total mass or volume studied.
Due to the above, concentration and rate of reaction are intensive parameters and they do not depend of the total mass or volume studied.
