3) The graph below represents the relationship between time and temperature as heat is added
at a constant rate to a sample of a substance.
Temperature
В.
Time
During interval AB which energy change occurs for the particles in this sample?
A)
The potential energy of the particles increases.
B)
The potential energy of the particles decreases.
C)
The average kinetic energy of the particles increases.
D)
The average kinetic energy of the particles decreases.

C: The average kinetic energy of the particles increases.

Explanation:

As the heat energy increases, the temperature rises and cause the

average kinetic energy of the particles increases.

But you should upload the graph that was provided with the question

answer: the value of enthalpy change will be -152.80 kj.

solution:

pressure = 1atm , temperature = = 298 k

given that pressure and temperature are same in both gases , the number of moles of both gases can be determined by the ideal gas equation.

according to reaction 3 moles no are reacting with 1 mol of ,then 0.49 mol of no will react with moles of ozone that is 0.16 moles of ozone. since, no is limiting reagent and is an excessive reagent.

enthalpy change for the reaction between the given volumes of the gases is :
