Two conditions must both be met for a collision between an NO2 molecule and a CO molecule to result in a reaction. State these two conditions.
Nitrogen dioxide is in equilibrium with colourless dinitrogen tetroxide in the gas phase. N2O4(g) ⇌ 2 NO2(g) State the expression for the equilibrium constant, Kc, of this equilibrium.
Consider the formation of gaseous nitrogen dioxide from liquid dinitrogen tetroxide. N2O4(l) → 2 NO2(g) ΔH⊖ = +85.9 kJ mol−1 (i) Calculate the entropy change of the reaction, ΔS⊖, in…
The graph shows the first six successive ionization energies of an element. In which group of the periodic table is the element? A. 13 B. 14 C. 15 D. 16
(i) State the IUPAC name of Compound B. (ii) Both compounds are liquids at room temperature. Identify the strongest intermolecular force between molecules of Compound B. (iii) State how many σ (sigma) bonds and how many π (pi) bonds one molecule of Compound A…
Compound B can also be made by the hydration of an alkene. The same reaction also gives a smaller amount of the isomer 3-methylbutan-2-ol, (CH3)2CHCH(OH)CH3. (i) Draw the structural formula of the alkene that is needed. (ii) Explain why the reaction…
Deduce what would be observed when each of Compound B and pentan-2-ol is warmed separately with acidified aqueous potassium dichromate(VI).
Bromoethane can be converted into ethanol: CH3CH2Br + HO− → CH3CH2OH + Br− (i) Identify the type of reaction. (ii) Outline what must be true of a collision between reacting particles for a reaction to occur. (iii) Explain the mechanism of this…
