WebFeb 26, 2014 · 1 Answer. Sorted by: 7. We assume 1 st order kinetics in hypochlorite and 1 st order kinetics in the color. Putting this in the equation we get the following: d [ Red] d t = − k [ Red] 1 [ bleach] 1. Because you keep the concentration of bleach the same throughout the trial, you can write. k obs = k × [ bleach] WebCompute and interpret the residual for the point (-0.2, 5.1). The observed x value is -0.2 and the observed y value is 5.1. The formula for the residual is \(e=y-\widehat{y}\) We can compute \(\widehat{y}\) using the regression equation that we have and \(x=-0.2\) \(\widehat{y}=6.5+1.8(-0.2)=6.14\)
