An arrow is fired at a target on a high wall. How does the energy change between the moment the arrow is fired and the moment it
hits the target?
The potential energy and kinetic energy remain the same.
The potential energy decreases as kinetic energy increases.
The kinetic energy decreases as potential energy increases.
The kinetic energy remains at zero, but potential energy increases

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 :
