Surface Area and Rate of Reaction Investigation

Surface Area and Reaction Rate Study Objective - Determine how the surface area of ​​marble chips (CaCo 3) affects the reaction rate in hydrochloric acid. Below are two plots of hydrogen ion and atomic layer, the other one is hydrogen ion overflow. Device list - Using the equipment used in this experiment, we will examine how the surface area of ​​the marble chip (caco 3) affects the reaction rate in hydrochloric acid. Beaker, duct, scale, ceramic holder, plastic tray.

The reaction rate is not always the same. There are several factors that influence the reaction rate: These factors are as follows. Concentration Temperature Area Surface Pressure Catalyst I conducted a preliminary survey using a preliminary plan before doing a survey. This can help you analyze whether the method I am using is appropriate and can show the necessary changes to the final result. To investigate, I need some solid reactants and liquid reactants. The solid reactants I use are marble chips - calcium carbonate

Factors influencing the reaction rate include concentration, temperature, surface area change or catalyst addition. This experiment will use hydrochloric acid and magnesium rods to specifically study the effect of changes in reactant concentration on reaction rate. The concentration of HCl acid solution was controlled by serial dilution. In particular, in the experiment, we will explore how the pressure changes as the above reaction progresses. Since the reaction produces hydrogen as product, higher pressure occurs in the limited space of the tube and the pressure sensor measures the reaction rate. After the reaction begins, each test gathers approximately 20 seconds of data to make a general trend (pressure versus time graph)

Reaction rate is a measure of reaction rate. There are many factors that may affect reaction rate. For example, solution concentration, temperature, surface area, catalyst, gas pressure, stirring etc. I decided to choose the temperature as a variable of my change to study the reaction rate. I estimate that the higher the temperature the faster the reaction. This is because as the temperature rises the molecular velocity increases, so more activation energy collides and reacts. At higher temperatures, the particles move faster, so the reaction becomes faster and slowly drops until tablet runs out. My prediction is also based on the experiment I conducted last year, ie reaction speed and temperature.
