Factors Affecting the Decomposition of Marble Buildings by acidic RainBackgroundAcid RainNitrogen acids and sulphur dioxides shine out of tall chimneys andvehicles. These go into the air, and air currents carry the gases out, and they react with piddle vapour and oxygen. This produces H2SO4(sulphuric acid) and HNO3 (nitric acid). The acids become part of acloud, and it falls down to earth, as acid rain or snow. This butt end endup miles away from the original source. The acid rain re move aroundsnutrients from soil, so plants can not halt to them, so this eventuallykills surrounding die. It can overly get into lakes and rivers, whichcan kill weight. The same is true for acid snow as it kills fish inrivers and lakes.Rates of answersThis is how quick a answer is, you can consider out the rate of a reaction by seeing how ofttimes of it is used up in a particular amount oftime. You could in addition measure how much is produced as a result of thereaction in a particular amoun t of time.Reactions take place because of conflicts, the particles (can beatoms, ions or molecules) collide, and a reaction occurs betweenparticles. If in that location are much oppositions, the reaction will be muchquicker. But it in any case depends on whether the collision has enough muscle, to be no-hit. If there is not enough energy, whence thecollision will be unsuccessful, but if there is, it will besuccessful, and a reaction will occur. Unsuccessful collisions takeplace when the activation energy is not reached. The activation energyis the amount of energy needed for a successful collision.There are factors which affect the rate of a reaction, and also if thecollisions are successful or not. Temperature rise gives particlesmore energy, and as thy move around more and much quicker they havecollisions. Also it gives particles more energy, so that when theycollide the collisions are more successful. Both these things meanthat there is a faster reaction rate. But, if tem perature decreasesthere is a slower reaction rate, as there is less energy. If there islarger surface area, it also means that reactions are quicker. Thereason for this is that there are more particles undecided to take partin collisions. So the more collisions means, more successfulcollisions, and a faster reaction rate. If surface area is decreased,then there are fewer exposed particles, therefore a slower reactionrate.Also concentration, affects reaction rate. In gases it is thepressure. If there is a greater concentration, then there are moreparticles in the same volume.
