Question

Identify the conjugate base of HSO_4^- H_2SO_3 H_2SO_3 SO_4^2- H_2O OH^- A rate constant for u particular reaction is 0.0090 s^-1. What is the overall order of this reaction? 1 4 0 2 3 The reaction 2SO_3(g) leftharpoonoverrightharpoon 2SO_2(g) + O_2(g) is endothermic. If the temperature is increased, no change will occur in K_e. the pressure will decrease. K_e will increase. K_e will decrease. more SO_3 will be produced. In general, which of the following types of solids would be the most soluble in carbon disulfide. CS_2? metallic nonpolar molecular network covalent ionic polar molecular For which of the following reactions are the numerical values of K_p and K_c the same? 2SO_2(g) + O_2(g) rightharpoonoverleftharpoon 2SO_3(g) N_2(g) + O_2(g) rightharpoonoverleftharpoon 2NO(g) H_2(g) + I_2(g) rightharpoonoverleftharpoon 2HI(g) 1 and 2 only 1 only 1, 2, and 3 2 only 2 and 3 only Which one of these salts will form a neutral solution on dissolving in water? NaCN NH_4NO_3 KNO_2 FeCl_3 NaCl For the following reaction at equilibrium, which change will cause the equilibrium to shift to the left? 2NOBr(g) leftharpoonoverrightharpoon 2NO(g) + Br_2(g), delta H degree_rxn = 30 kJ/mol Remove some Br_2. Increase the container volume. Add more NOBr. Decrease the temperature. Remove some NO.

Explanation / Answer

1) The conjugate base for HSO4- is SO42- (option c)

Reason:

Even it has a negative charge, but it will never accept a H+ ion to form H2SO4. This is because the sulfuric acid H2SO4 is a strong acid and completely dissolves in water.
