Knowledge about the speed of chemical reactions is extremely important for industrial production, especially when optimizing a process. In this sense, strategies can be developed based on changes in the surface area, concentration of reactants, system temperature, and the use of catalysts. Considering this information, analyze the following statements: I. The frequency and orientation of collisions between the reacting species, as well as the amount of energy in the system, are determining factors for the formation of the activated complex. II. The use of catalysts provides an alternative pathway for the formation of the activated complex with lower activation energy, consequently increasing the reaction rate. III. Exothermic transformations are more advantageous because they release energy during product formation, thereby eliminating the need to supply energy to the reactants. Is it correct to assert that:
Suppose the reduction of nitric oxide proceeds by the following mechanism: step elementary reaction rate constant 1 H,(g) + 2 NO(g) → N,0(g) + H,0(g) k1 2 H2(9) + N,0(9) → N2(9) + H,O(g) Suppose also k, «k,. That is, the first step is much slower than the second. Write the balanced chemical equation for the overall chemical reaction: Write the experimentally- observable rate law for the overall chemical reaction. rate = k U Note: your answer should not contain the concentrations of any intermediates. Express the rate constant k for the overall chemical reaction in terms of k1, k2, and (if necessary) the rate constants k.1 and k-2 for k = the reverse of the two elementary reactions in the mechanism.
Why does the product (a•b), rather than the sum (a + b) appear in the Law of Mass Action? This is sometimes brought up to demonstrate how/why nonlinear terms arise in differential equations. The law of mass action states that The rate of a chemical reaction involving an interaction of two or more chemical species is proportional to the product of the concentrations of the given species. This is NOT an assignment...I'm just curious and trying to understand mathematical relations better. Thanks!
