Webconcentration if, after 2.0 minutes, the reactant concentration is 0.062 M? (a) 0.84 M (b) 0.069 M (c) 0.091 M (d) 0.075 M (e) 0.13 M 10. Given that a reaction absorbs energy and has an activation energy of 50 kJ/mol, which of the following statements are correct? (Hint: Draw the potential energy diagram.) WebIn each succeeding half-life, half of the remaining concentration of the reactant is consumed. Using the decomposition of hydrogen peroxide ( Figure 12.2) as an example, we find that during the first half-life (from 0.00 hours to 6.00 hours), the concentration of H 2 O 2 decreases from 1.000 M to 0.500 M. WebSince the reactant concentration decreases as the reaction proceeds, Δ [H 2 O 2] is a negative quantity. Reaction rates are, by convention, positive quantities, and so this negative change in concentration is multiplied by −1.
