- Define stability from both a kinetic and thermodynamic perspective. Give examples to show the differences in these concepts.arrow_forwardAmoxicillin is an antibiotic packaged as a powder. When it is used to treat babies and small animals, the pharmacist or veterinarian must suspend it in water, so that it can be administered orally with a medicine dropper. The label says to dispose of unused suspension after 14 days. It also points out that refrigeration is required. In the context of this chapter, what is implied in the latter two statements?arrow_forwardIf the volume of a container for the reaction A+2B=C is suddenly reduced to ½ its original volume with the moles of A, B and C maintained constant, the rate will increase by a factor ofA. 2B. 4C. 8D. 16arrow_forward
- Write down the kinetic equation for a simple reaction in a homogeneous medium 2A + B = 2C. Indicate the general and in relati on to all reactants reaction ordersarrow_forwardHere is the correct statement for Qc and Kc for a certain reaction. Qc value is determined by the concentrations of reactants and products at a particular moment rather than by the temperature, but Kc value stays the same at a certain temperature regardless of the concentrations. For the following reaction at 20oC, the Qc value at a particular time is equal to 3.5 x 10‒5 3A(aq) + B(aq) ⟶ 2C(aq) + D(aq) Kc = 5.5 x 10‒5 If the reaction temperature is suddenly increased to 40oC without affecting the concentration of each component in the system, which of the following is a correct prediction about Qc and Kc at this particular time at 40oC? Q ≠ 3.5 x 10‒5, K = 5.5 x 10‒5 Q ≠ 3.5 x 10‒5, K ≠ 5.5 x 10‒5 Q = 3.5 x 10‒5, K ≠ 5.5 x 10‒5arrow_forwardA certain reaction has an activation energy of 63.0 kJ mol−1kJ mol−1 and a frequency factor of A1�1 = 5.20×1012 L mol−1 s−1L mol−1 s−1 . What is the rate constant, k�, of this reaction at 29.0 ∘C∘C ? Express your answer with the appropriate units. Indicate the multiplication of units explicitly either with a multiplication dot (asterisk) or a dash.arrow_forward
- Consider the reaction a A(aq) → bB(aq) (1) Where a and b are stoichiometric coefficients for the balanced chemical reaction The average reaction rate r can be measured if the concentration change of the reagents or products is known: 1 ΔΙΑ 1 Δ r = and r = At b At a where A and B notate the concentration of A and B in solution, and A is always defined as the difference between "final" and "initial": A[4] = [A],2 - [4],1 and At = t2 – t . - A particular case of eq. (1) could be A(aq) → 2 B(aq) If the initial concentration of B is 0.2569 mol L1, and after 415.6 s it increases to 0.4633 mol L1, what is the rate of the reaction in mol L1s? mol L-1 s1. (Use scientific notation)arrow_forwardPeroxynitric acid (HOONO2) is an unstable molecule that decomposes to nitric acid and oxygen: 2HOONO2(aq) → 2HNO3(aq) + O2(g)When the concentration of peroxynitic acid is graphed against time, the resulting plot is curved, but if the logarithm of this concentration is plotted, we instead get a straight line. Based on this, which statement is true? a) This decay is a second order in peroxynitric acid. b) The slope of the straight-line graph is the rate constant. c) One needs the concentration of peroxynitric acid to calculate its half-life. d) The rate law appears to be of the form -Δ[HOONO2]/Δt = k[HOONO2].arrow_forwardChlorine dioxide (ClO₂) is a disinfectant used in municipal water treatment plants. It dissolves in basic solution producing ClO3 and ClO₂": 2 CLO₂(g) + 2 OH (aq) → ClO3(aq) + ClO₂ (aq) + H₂O(l) › The following kinetic data were obtained at 298 K for the reaction.
