Abstract

Reaction rate is fundamentally defined as the change in the concentration of reactants or products perunit time, and is known to be influenced by several determinants, including surface area, temperature,catalysts, and reactant molarity or concentration. The present study specifically investigates the validityof the widely accepted principle that temperature plays a significant role in modulating reaction rates.Experimental variations were introduced, both in terms of temperature levels and the types of chemicalmixtures employed. The findings confirm that temperature indeed accelerates gas generation across alltested reaction systems. However, in mixtures exhibiting higher viscosity, gas formation proceeds moreslowly due to reduced molecular mobility. Consequently, in the softener–baking soda system, the onsetand progression of gas evolution show noticeable differences compared to less viscous mixtures.

Abstract

This study aims to examine the electric current strength of sugar mixed with various electrolyte and non-electrolyte solutions. The research employed an experimental approach using vinegar, lime extract, coffee solution, salt solution, and 70% alcohol combined with sugar solutions. A battery system and a digital multimeter were utilized to measure the resulting current in each mixture. The findings indicate that increasing the amount of sugar leads to a reduction in current strength, whereas decreasing the sugar content results in a higher current output.
