Investigate the effects of the concentration of reactants on rate of reaction

In this experiment, we examine the effect of reactant concentration on reaction rate. In this experiment we are planning to investigate the effect of reactant concentration on reaction rate. Specifically, we will examine the influence of hydrochloric acid concentration change when sodium thiosulfate and hydrochloric acid are reacted. Collision theory describes the details of how reactions work at the molecular level. The theory of collision explains that collisions between reactant particles involved in the reaction must collide to react.

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)

The reaction rate requested to investigate the influence of various factors such as concentration and temperature on reaction rate can be divided by the time required for reaction It is the reactant loss rate during chemical reaction or the product production speed . Collision theory is based on the fact that the increase in concentration, temperature, surface area and catalyst usage in the reaction increases the reaction rate by increasing the collision speed between reactant particles, increasing the success rate of collisions between reactants, He said that. There is another factor that affects the reaction rate, but the pressure is the only gas.
