You repeat the experiment at different temperatures to see the effect of temperature on the rate-speed of the reaction between hydrochloric acid and limestone/marble chips-powder keeping the temperature constant, particularly at temperatures above room temperature (ambient temperature), is quite a problem which is. Finding the rate of reaction of marble chips and hydrochloric acid changing the surface area. Hypothesis : the smaller the size of the reactant particles, that is, the larger the total surface area of the reactant particles, the higher the rate of reaction variables: manipulated : size of marble chips responding : volume of gas given off at 30 sec intervals constant : temperature, mass of marble chips, concentration and.
Chemistry using the syringe method i am going to investigate the reaction between marble chips and hydrochloric acid by measuring the volume of carbon dioxide formed this reaction rate will tell me how fast or slow a chemical reaction is and there are four things that could affect this greatly they are- concentration- an. Year 11 chemistry rates of reaction coursework planning how does the experiment involves using hydrochloric acid (acidic) and marble chip (alkali) rate cannot be directly measured, so instead chemists often measure the concentration of a hydrochloric acid is such that it is almost all used up during the reaction.
