Chemical reactions involve the breaking of chemical bonds, the rearrangement of elements, and the formation of new bonds. In order for a chemical reaction to take place, the particles must collide. The collision between the molecules in a chemical reaction provides the needed to break the necessary bonds so that new bonds can be formed. Successful collisions result in a chemical reaction that or energy. If the products have lower energy than the reactants, the reaction is and energy is If the reactants have lower energy than the products, the reaction is and energy is

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 :

sorry i was late, but i don't know what assignment your talking about, i'm in flvs as well, im in earth space science. but u are behind pace bc every class should be in the 3's or 4'
