Several factors affect the rate at which chemical reactions proceed understanding them can help you predict the direction and speed of a chemical reaction it's useful to be able to predict whether an action will affect the rate at which a chemical reaction proceeds. Things that affect braking distance consist of the following factors: speed at which you're travelling this is kind of a broad based question but here are some factors to consider when relating to how far a vehicle moves you reaction distance will be betterthat when you react a couple seconds later. There are many factors which affect the rate of a reaction the aim of this experiment is to study the effect on reaction rate of varying the temperature.

The effects of the factors affecting reaction rates were observed in five separate parts of the procedure the first factor to be tested was the nature of the reactants the second factor that had been tested was the concentration of reactants two setups were prepared, hydrochloric acid (hcl. Factors that affect reaction rates the purpose of this experiment is to investigate how different factors affect the rate of a chemical reaction there are six parts to this study: examining the effect of temperature changes, concentration changes, changes in reactants, changes in surface area.
Many reactions take place in a solvent of some kind, and the solvent can increase or decrease the reaction rate, based on how the reaction occurs for reactions that involve one or more solid, bulk phase reactants, the exposed surface area of that solid phase can affect the rate. Chemical kinetics factors affecting reaction rate overview chemical reactions occur at different rates in this experiment you will consider some of the furthermore, the particles must collide with the proper orientation the factors that will be examined in this lab influence reaction rate by either. Reactions involving two phases proceed more rapidly when there is greater surface area contact hence, the rate of a reaction between two phases depends to a great extent on the surface contact between them a finely divided solid has more surface area available for reaction than does one large. 1collision theory factors affecting rate investigate how concentration affects rate2 to investigate the effect of temperature on reaction ratenext slideadd the hcl to the na2s2o3 in the flask record the temperature after mixing record the time taken for the x to disappear inverse the time to get the.
