WebIt's done so because to find resistance according to Ohm's law, we are dividing the voltage by current. So when we find the slope, which is. (Δy/Δx) of the straight-line graph (i.e., resistance), we need the voltage to be on the Y-axis (numerator of the fraction) and current on the X-axis (denominator). Hence, the other way round. WebFeb 12, 2024 · In 1889, Svante Arrhenius proposed the Arrhenius equation from his direct observations of the plots of rate constants vs. temperatures: (6.2.3.4.1) k = A e − E a R T. The activation energy, E a, is the minimum energy molecules must possess in order to react to form a product. The slope of the Arrhenius plot can be used to find the activation ... WebJul 24, 2024 · The reason that V = E d only applies when there is a constant field is that the voltage is actually the integral of the electric field with respect to distance. V = ∫ a b E ⋅ d r. If E is constant, you can pull it out of the integral and the result is just V = E ( b − a) = E d. You can think of it like the electric field being the ... dhl featherstone
