The decomposition of hydrogen peroxide, H2O2, is catalyzed byBr– ions according to the following mechanism:
H2O2 + H H3O2 + forward rate constant k1, reverse rateconstant k–1
H3O2 + Br –→ HOBr + H2O forward rate constantk2
HOBr + H2O2 → H+ + H2O + O2 +Br– forward rate constant k3
Assume that the first step is in rapid equilibrium, and theintermediate HOBr is in steady-state. If we
measure the rate of O2 production (the rate of the third step),predict the rate law that would be observed based on thismechanism.

Percent ionization for a weak acid (ha) is determined by the following formula: percent ionization=[ha] ionized[ha] initial×100%for strong acids, ionization is nearly complete (100%) at most concentrations. however, for weak acids, the percent ionization changes significantly with concentration. the more diluted the acid is, the greater percent ionization.a certain weak acid, ha, has a ka value of 9.4×10? 7.part acalculate the percent ionization of ha in a 0.10 m solution.part bcalculate the percent ionization of ha in a 0.010 m solution

Which is true about metals used for jewelry, such as platinum and gold? a. they have low flammability. b. they have low reactivity. c. they have high flammability. d. they have high reactivity.

Choose one literary selection from this semester in which you think the setting has a great impact on the work. in a full paragraph name the work, describe the setting, and explain why it is so important to the overall story or poem.
