Which of the following is NOT an example of a change of state? * HELP PL
Plants using photosynthesis to produce food.
Liquid water in perspiration changes to a gas when it evaporates.
An ice cream cone melts, forming a liquid.

Plants using photosynthesis to produce food.

the icecream one is not an example

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 :
