In neutral solution containing only hydrogen peroxide and iodide ion, a different net chemical reaction occurs: 2 H,0, - 2 H,0 + O;{g) (2) The following three-step reaction mechanism has been proposed to explain reaction (2): Step 1: (slow) H,O, +1 - OH + HOI Step 2a: (very fast) OH + HOI - 10- + H,0 H,0 + 10 I + H,0 + 0;(g) 2 H202 → 2 HzO + OLCJ Show that when you sum the three reaction steps the net result is reaction (2): Step 3a: (fast) What would be the expected rate law for the reaction mechanism, assuming that the rate of reaction (2) is limited by the slow Step 1?

calculate the concentration for a reaction A—-> product after 7.0 minutes knowing that the initial concentration is 2.4 M and the rate constant is 3.2×10-3 M-1 sec-1

1- In phosphorus for the reaction:   4 PH3 (g) --> P4 (g) + 6 H2 (g) The rate of P4 is 8.0 M/s. What is the rate in phosphine, PH3 ?   2- Same phosphorus reaction as previous:   4 PH3 (g) --> P4 (g) + 6 H2 (g) The rate of P4 is 8.0 M/s. What is the formation rate in hydrogen H2 ?

1) Consider the reaction below. If the concentration of B doubles, what happens to the concentration of A, in the same length of time? 2 A B + 3 C 3 ㅎd[A] doubles triples reduces to one-halfreduces to one-third A -LUCA] = d[B] = 1 A[W) jun 3 =2= 2 dit d+ ↑ dt2) A reaction proceeds during which the half-life of the reactant, A, is shown to increase The rate over time. What is the order with respect to A2 concentrations of A retubes to A? i one warter for ro order realtion not predictable dictory =-4 Rate - +42 = K[AO] +1/2 of 1 САОЈ [A] zeroth first second this is not possible, as half-life would be constant the order is not predictable based on this information A 2 B + C 3) What is the order for the alpha decay of lead-210? All radioactive decay zeroth first second the order is not predictable based on this information quadruples reduces to one-quarter 2 ¿CB] =2 dUB] of zeroth 4) Given the plot below, determine the reaction order for 2 A C. first second d+ reactions are first orter…
