When looking at an energy diagram, how can you calculate the overall enthalpy change and activation energy? How can you determine if they are positive or negative?

43.452

step-by-step explanation:

284 times .153 = 43.452

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 :

it would be d. henry moseley

hope this !
