7. Record the ml of the gas. Also record the time when the reaction is over.
8. Clean the flask and do the same things (1. ~4.) with different amount of baking soda.

Also the rate of reaction increase.<br />-32385339725Graph1: relationship between baking soda and ml per seconds<br />The proportion of ml per seconds and velocity is to be amount of baking soda.<br />Analysis<br />According to this data, using 0.5g of baking soda, the average rate is 5.03 and, using 0.9g of baking soda, the average rate is 2.25. Therefore the average rate is almost 1/2. Also, the gap between 0.7g’s trial and 0.8g’s trial is the greatest.<br />Conclusion<br />As the data shows, it has positive slope. If the amount of the baking soda increases, then rate of the reaction faster.<br />Evaluation<br />It is difficult to decide when the reaction was enough to react, so it might occur the difference between the data. Also, gas might be gone because a stopper was closed the beaker slow after adding vinegar.<br />
![Yuki Yoshida<br />Chemistry Pd1<br />11/11/09<br />Rate of Reaction<br />Introduction<br />Rate of reaction is the reaction rate for a reactant or product in a particular reaction is intuitively defined as how fast a reaction takes place. In the reaction between baking soda and vinegar, the gas (carbon dioxide) formed by a chemical reaction. By measuring the volume of gas and time of the reaction, the rate of reaction could be observed. <br />Objective<br />Observe and measure the rate of a chemical reaction. Design and perform an experiment investigating how some factor affects the rate of a chemical reaction.<br />Procedure<br />,[object Object]](https://image.slidesharecdn.com/datatable-110503212523-phpapp01/85/Data-table-1-320.jpg)
