Taking the natural logarithm of the Arrhenius equation and rearranging the terms yields an equation that has the same form as the equation of a straight line (y = mx+b): ln (k) = -E a /R (1/T) + ln (A) In this case, the x of the line equation is the reciprocal of absolute temperature (1/T). So, when data is taken on the rate. Step 1: Calculate the mean of the x -values and the mean of the y -values. Step 2: The following formula gives the slope of the line of best fit: Step 3: Compute the y -intercept of the line by using the formula: Step 4: Use the slope m and the y -intercept b to form the equation of the line Using any two points on a line, you can calculate its slope using this formula. Let's use these two points to calculate the slope m of this line. A = (1,1) and B = (2,3) Subtract the y value of point A from the y-value of point B to find the change in the y value, which is 2 Put this pair of numbers (0, 5) into the chart. Now try another value for x, say x = 1. this gives y = -2x + 5 = -2 \times 1 + 5 = 3. Put the pair (1, 3) into the table. Do it again with x = -1 to give y = -2x + 5 = -2 \times -1 + 5 = 7. Put the pair (-1, 7) into the table. Continue for as many values of x as you feel is necessary Excel's new XLOOKUP will replace VLOOKUP, providing a powerful replacement to one of Excel's most popular functions. This new function solves some of VLOOKUP's limitations and has extra functionality. Here's what you need to know
