Changing the Rate of Reaction PART 1: PARTICLE SIZE Question: How does changing the particle size of marble (CaCO3) affect the rate of reaction when it is added to hydrochloric acid (HCl)? Hypothesis: If I change the particle size of marble to test how to change the rate of a chemical reaction‚ than the chemical reaction with the smallest marble particles will produce CO2 the quickest because the larger the surface area‚ the more place the hydrochloric acid will have to collide with the marble

The Relationship Between Work Rate And Oxygen Uptake During Incremental Submaximal Exercise Introduction Oxygen uptake () describes the rate at which oxygen is utilized by tissues (Burton et al‚ 2004). is determined by heart rate (heart beats each minute)‚ stroke volume (the volume of blood pumped from one ventricle each beat) and arteriovenous oxygen difference (difference in blood-oxygen content between arterial and venous blood). Oxygen is needed for respiration‚ the chemical process that

Erin Bolton Chemistry Lab Report April 29‚ 2015 Lab: Reaction Rates Introduction: In this experiment we studied the reaction of potassium persulfate‚ K2S2O8‚ with potassium iodide‚ KI. All chemical reactions have an energy barrier to overcome before the reaction will proceed. We will record data based on the concentration‚ temperature and catalyst for each experiment. Once this has been completed it will be graphed. Procedure: Due to the chemicals being used having hazard gloves are used
