<center><b>Rate of Reaction - Clock Lab</b></center> <br> Chemical Reactions<br> <br> <br> <br> <b>Effect of concentration on rate of reaction:</b><br> <i>Directions(Procedures)</i><br> <br> 1. Add the appropriate amount of Solution A (see table below for volumes) and amount of water to the 100ml beaker.<br> <br> 2. Pour out the appropriate amount of Solution B into 25ml graduated cylinder.<b>DO NOT ADD TO 100ml BEAKER UNTIL HAVE STOPWATCH</b><br> <br> 3. Add all Solution B into 100ml beaker at once, start stopwatch and swirl solutions until "solution turns blue". <br> <br> 4. Record time.<br> <br> 5. Dispose of solution into sink and clean 100ml beaker. <b>Use only one graduate cylinder for each solution for all trials</b><br> <br> <table bgcolor=beige border=2> <tr> <th colspan=8 align=center>Data Table: Volumes of Solutions vs. Reaction Rate</th> <tr> <tr> <th>Trial #</th> <th>Solution A</th> <th>Water</th> <th>Solution B</th> <th>Rate of Rxn(sec) <tr> <tr> <th>Trial 1</th> <th>10.0ml</th> <th>0.0ml</th> <th>10.0ml</th> <th>______________</th> <tr> <tr> <th>Trial 2</th> <th>9.0ml</th> <th>1.0ml</th> <th>10.0ml</th> <th>______________</th> <tr> <tr> <th>Trial 3</th> <th>8.0ml</th> <th>2.0ml</th> <th>10.0ml</th> <th>______________</th> <tr> <tr> <th>Trial 4</th> <th>7.0ml</th> <th>3.0ml</th> <th>10.0ml</th> <th>______________</th> <tr> <tr> <th>Trial 5</th> <th>6.0ml</th> <th>4.0ml</th> <th>10.0ml</th> <th>______________</th> <tr> <tr> <th>Trial 6</th> <th>5.0ml</th> <th>5.0ml</th> <th>10.0ml</th> <th>______________</th> <tr> </table> <br> <br> <br>
