Report Table IC.1: Reaction Times Reaction times for experiments A1-A7 Determining Activation Energy Report Table IC.2: Reaction Times for Hot and Cold Solutions Measurements of temperature and initial rates for reactions A3cold and A3hor Make sure your lab instructor has scanned your QR code before you leave the lab.

Average value of exponent (rounded) =1 V1. CALCULATIONS FOR DETERMINING THE RATE CONSTANT: Next, you need to calculate the rate constants for trials A1-A7 (a total of 7 entries, report table IC.8) and for warm and cold reactions (a total of 4 entries, report table IC.9). Be careful when calculating all of these. Try to use 3-4 significant figures for this calculation. Use the example below to calculate the exponent. FORMULAS TO USE TO PERFORM THE CALCULATIONS: rate=k[I]a[BrO3]b[H+]c EXAMPLE CALCULATION FOR A1 (same for A2-A7, warm and cold, trials 1 and 2): For example, if your values of a=1,b=2 and c=3 (which are just hypothetical values) and using the A1 rate is 1.587107Ms1 and initial rates are thiosulfate ion [S2O32]=0.0001, iodide ion [II]=0.0018M, bromate ion [BrO3]=0.0072M and acid [H+]=0.0018M, then: k=rate/[1]2[BrO3]b[H]c=(1.587107Ms1)/(0.0018M)1(0.0072M)2(0.0018M)3,sok=(1.587101Ms1)/(0.0018M)(0.0000518M2)(5.832108M3)=k=(1.587107Ms1)/(5.4371015M6)=2.918107M5s1 VII. CALCULATIONS FOR DETERMINING THE AVERAGE RATE CONSTANT: Next, you need to calculate the average value of rate constant (A1 to A7 but NOT warm or cold), average value of rate constant cold, and average value of rate constant warm (a total of 3 entries). FORMULAS TO USE TO PERFORM THE CALCULATIONS: Average value of rate constant (A1-A7) =( sum of A1-A7) )/7 Average value of rate constant (cold) =( trial 1+ trial 2) /2 Average value of rate constant (hot) =( trial 1+ trial 2) /2 VIII. CALCULATIONS FOR DETERMINING THE ACTIVATION ENERGY: Next, you need to calculate the m and the Ea. Calculate m by graphing ln(k) vs 1/T and using excel to get your trendline (v=mx+b, where m will equal your slope). Use your three values of k from IIVII and the temperature of the reagents at room temperature, temperature of ice water, and temperature of warm water. When you graph this, your slope = m. Then EE=mR is used to determine the activation energy. Complete the following table by calculating the initial rate of reaction for each experiment.
