In radical chlorination of alkanes, non-equivalent hydrogens react with chlorine atoms at different rates. At 35 °C, primary, secondary, and tertiary C-H bonds react at relative rates of 1: 3.9 : 5.2 respectively. These are conditions of kinetic control where product ratios are determined by relative rates of formation. For example, if A is formed twice as fast as B, the A:B product ratio will be 2. Consider chlorination of the alkane below at 35 °C. 1. Specify the most reactive C-H bond(s), a-c. Two non-equivalent C-H bonds of comparable reactivity should be separated by commas, i.e. a,c. 2. Specify the site of chlorination in the major monochloro substitution product, a-c. Two products that form in comparable quantities should be separated by commas, i.e. a,c

It has been found that in acid solution (greater than 1M H3O+) the rate expression rate for the reaction of H2O2 with I- is of the form : rate= k2[H2O2][I-][H3O+], where k2 = .25L2*mol-2*s-1 at 25C. Therefore, the rate law over the whole range of acidity from very acid solutions to a neatural solution is given be a two-term rate expression: rate = k1[H2O2][I-] + K2[H2O][I-][H3O+] Where K1 has the value of .0115L*mol-1*s-1 at 25C. Compare the relative magnitudes of these two terms under the conditions employed in your rate measurements for mixture 1. ( you should find what that the second term makes a negligible contribution to the reaction rate at H3O+ smaller than 3 x 10 -4) mixture 1 concentrations H2O2 = 5.3 x10-5 I- = 8.3 x 10 -6 H3O = 10-5
Below is a proposed mechanism for ClO–(aq) reacting with I–(aq) in the presence of OH–(aq). ClO- +H2O --> HOCl +OH- (fast, reversible)I- +HOCl --> HOI +Cl- (slow)HOI + HO- --> IO- +H2O You are trying to show that the rate law for this proposed mechanism matches an experimentallydetermined one. What is the expression for koverall or k’ for the proposed mechanism?Note: When writing an expression, H2O is not involved (just don’t include it).

A particular reactant molecule "R" is capable of undergoing condensation and forming either a single closed loop (R-> L) or long chain polymer (R+R+R ->P). The rate law for the loop forming reaction is rate(loop) = kLoop[R]; the rate lw for the polymerization reaction is rate(poly) = kpoly[R]^2 a) a beaker with a starting concentration of R equals 0.50M at 60degrees. After 75 minutes of reacting, the concentration of L is 0.10M. Assuming no change in volume or temperature, find k(loop) b. At the 75 minute mark the remaing concentration of R is 0.398M. What can you conclude (qualitatively) about the magnitude of k(poly) relative to k(loop)?
Prof. Neiman and Prof. James were first to discovered in 1973 that chlorofluorocarbons (CFCs) were depleting the Earth’sozone layer when released into the atmosphere. Once they reach the stratosphere, Clis released from the CFCs molecules by interaction with UV light. Free Cl atoms areable to react with ozone in a catalytic cycle that converts O3into the more stable O2.It is estimated that a single Cl atom is able to react with∼100000 O3molecules.Although CFCs production was banned in 1996, there are still a substantial numberof motor vehicle air conditioners (MVACs) that use CFC-12 (CF2Cl2) as refrigerant.The average CFC-12 emission rate from operating MVACs has been estimated tobe 59.5 mg per hour per vehicle (Zhang et al.Environ. Sci. Technol. Lett.2017).How much chlorine, in kg, is added to the atmosphere in a year due to 100 millionMVACs using CFC-12 as refrigerant?
