Investigating How Concentration of Acid Affects the Reaction Between Calcium Carbonate and Hydrochloric Acid - Investigating How Concentration of Acid Affects the Reaction Between Calcium Carbonate and Hydrochloric Acid Introduction ============ According to the collision theory temperature, concentration, surface area and catalysts all affect rates of reaction as shown in the diagrams below. Increasing any of these should increase the number of collisions and so increase the reaction rate up to an optimum point. Increasing the temperature causes the particles to collide with more energy and more frequently, thereby increasing the reaction rate....   [tags: Papers] 3026 words

Acid Rain - ... Once a lake has become acidic, the aquatic microorganisms will suffer, the first ones being crayfish and clam. The backbone to the lake’s food chain is the plankton-minute organisms which are also affected. Fish would suffer from the incapacity to regulate their body chemistry, a reduction in egg deposits, a DNA alteration in young fish and vulnerability to natural diseases. As aquatic life diminishes, water-eating birds will begin to disappear simultaneously.

What Affects the Rate of Reaction? - What Affects the Rate of Reaction. Hypothesis To form a reaction the particles must collide in high speed. The faster the particles collide the more kinetic energy is produced. This produces a bigger reaction. There are five key variables that affect the rate of a reaction (in this case with a solid and a solution): * Change in temperature An increase in heat energy within the particles leads to more kinetic energy. Therefore there is more collision of particles and it increases the rate of the reaction....   [tags: Reaction Rates Energy Science Essays] 2334 words

Factors Affecting the Decomposition of Marble Buildings by Acid Rain - Factors Affecting the Decomposition of Marble Buildings by Acid Rain Background Acid Rain: Nitrogen acids and sulphur dioxides come out of tall chimneys and vehicles. These go into the air, and air currents carry the gases away, and they react with water vapour and oxygen. This produces H2SO4 (sulphuric acid) and HNO3 (nitric acid). The acids become part of a cloud, and it falls down to earth, as acid rain or snow. This can end up miles away from the original source.

How does Concentration affect the rate of reaction between Magnesium and Hydrochloric acid? - How does Concentration affect the rate of reaction between Magnesium and Hydrochloric acid. Secondary resources: Chemical reactions only occur when reacting particles collide with each other, with sufficient energy to react, this is called the collision theory. The minimum amount of energy required to cause this reaction is called the Activation energy. There are four main factors which affect the rate of reaction. The first factor is: Temperature of reactants: When the temperature increases the particles move around faster (because they have more energy)....   [tags: GCSE Chemistry Coursework Investigation] 1743 words
