  Abstract
  This research focused on Kenya`s life cycle cost analysis (LCCA) of yellow oleander (Thevetia peruviana) for biodiesel. It also evaluated the feasibility of biodiesel production from yellow oleander at a 100,000 t/year plant in Kenya using synthesized eggshell-derived waste nanocatalysts. The production costs considered included Estimated Fixed Capital Investment (FCI), Total Capital Investment (TCI), and Total Manufacturing Cost (TPC). The annual production cost was 9,487,834,956.00 (80,809,428.13- dollars/year). The estimated production cost of biodiesel from yellow oleander is 241.65 KES (1.96 dollars/L). In contrast, the estimated cost of the B20 biodiesel blend was KES 163.34 or (US 1.32 - dollars/L), which was 0.53 % cheaper than petrodiesel at 164.21 KES/L or (US 1.33 -dollars/L). Based on the annual production cost, the total raw material cost and labor cost were 74.38% and 0.008%, respectively. In addition, revenue from glycerin sales reduced biodiesel production costs by 13.67%. Labor costs accounted for 0.008% of production costs, making the production of biodiesel from yellow oleander less labor-intensive. The return on investment (ROI) of 810.32% exceeded the acceptable minimum return (MARR), indicating that biodiesel production from yellow oleander is feasible. This study also calculated the energy balance based on the different soil types used when planting yellow oleander plants. In normal soil, the total energy input was 120,729,624.96 MJ. In normal soil, the energy output was 840,000,000.00 MJ and the energy output/input ratio was 7.16. Accordingly, the estimated net energy number was positive, showing high values for the soil used.

  Abstract
  Strong electrolytes are totally ionized at all dilutions; hence the Ostwald`s dilution law only applies to weak electrolytes and completely fails in the case of strong electrolytes. Water molecules surround and solvate the ions, weakening the strong electrostatic interactions between them, which causes the ions in the solid to separate and scatter equally throughout the solution when ionic substances dissolve in water. Under normal circumstances, ionic compounds will dissociate almost entirely when dissolved, which is why they are categorised as strong electrolytes. This process represents a physical change known as dissociation.1,2. In other words, when dissolved in water, they do not produce a lot of ions. They create a tiny current with their solutions. As the ions transition from their fixed and ordered positions in the crystal to the mobile and considerably more disordered states in solution, the system becomes more chaotic due to the loss of electrostatic attraction, which allows each hydrated ion in a dilute solution to move independently. Sometimes, the electrostatic interactions between the ions and water molecules are too weak, causing the crystal to become intractable because the increase in disorder cannot offset the energy needed to separate the ions. 3,4. That is, they produce relatively few ions when dissolved in water. Their solutions produce a small current. Therefore, unlike in a perfect solution, ions are not evenly distributed throughout the solution. In present research paper the study of deviation from the ideal behavior has been proposed through experimental outcomes.
