We could also use the statistical method of finding the equation of the regression line, which is: Y = a +bx (where y and x are the axis's) B = ((xI - (x)(yI - (y) ((xI - (x)2 a = (y - B(x Where (y = average of all y values (x = average of all x values xI = x value yI = y value Therefore, when an equation is formed, we can mathematically derive the gradient, as the gradient of the graph, mathematically is the constant in front of x, providing y has no constants. Thus B = ((xI - (x)(yI - (y) ((xI - (x)2 = 0.796 = 0.80 therefore, the order of reaction, with respect to the iodide ions is 0.80. Maximum error of reading an apparatus = maximum error x 100 Amount read Maximum error of 5 cm3 pipette = 0.1/ 5 x 100 = 2% Maximum error of ...
