WebJan 24, 2024 · Solution:- For the given reaction the rate could be written as: rate = Here the negative sign indicates a decrease in concentration of the reactants and the coefficients are inverted. For example the coefficient of is 2, so it is written as . From above expression, Let's plug in the value for the rate of decrease in concentration of ethylene. Hence the rate constant must have units of reciprocal seconds (s −1) to have units of moles per liter per second for the reaction rate: M·s −1 = M/s. B The only concentration in the rate law is that of cyclopropane, and its exponent is 1. This means that the reaction is first order in cyclopropane.
WebDec 9, 2024 · The first step in calculating molarity is to determine the number of moles in four grams of solute (sucrose) by finding the atomic mass of each atom in the solution. This can be done using the periodic table. The chemical formula for sucrose is C 12 H 22 O …
