(a) Use the following results to arrange the four metals, \(\mathrm{W}, \mathrm{X}, \mathrm{Y}, \mathrm{Z}\) in the vertical column on the right from the most active (at the top) to least active (on the bottom). \(\mathrm{W}+\mathrm{X}^{+} \rightarrow \mathrm{W}^{+}+\mathrm{X}\) most active \(\mathrm{X}+\mathrm{Z}^{+} \rightarrow \mathrm{X}^{+}+\mathrm{Z}\) \(\mathrm{Y}^{+}+\mathrm{Z} \rightarrow\) no reaction \(\mathrm{X}+\mathrm{Y}^{+} \rightarrow \mathrm{X}^{+}+\mathrm{Y}\) least active (b) Based on your series in part a, circle ALL the reactions below that you would expect to occur spontaneously as written. Explain. \(\mathrm{W}^{+}+\mathrm{Y} \rightarrow \mathrm{W}+\mathrm{Y}^{+} \quad \mathrm{W}^{+}+\mathrm{Z} \rightarrow \mathrm{W}+\mathrm{Z}^{+}\)

Step by step solution

01

Analyze given reactions

We have the following information given about the reactivity of metals W, X, Y, and Z: 1. W + X+ → W+ + X (W is more reactive than X) 2. X + Z+ → X+ + Z (X is more reactive than Z) 3. Y+ + Z → No reaction (Cannot deduce any reactivity information here) 4. X + Y+ → X+ + Y (X is more reactive than Y)

02

Determine the order of reactivity

Based on the given reactions, we can deduce the following order of reactivity: - W is more reactive than X (from reaction 1) - X is more reactive than Z (from reaction 2) - X is more reactive than Y (from reaction 4) Hence, the order of reactivity is W > X > Y > Z. (W is the most active, Z is the least active) #b: Determine spontaneous reactions#

03

Analyze given reactions in part b

Based on the reactivity ranking established in part (a), we need to determine if the following reactions occur spontaneously: 1. W+ + Y → W + Y+ 2. W+ + Z → W + Z+

04

Determine spontaneous reactions

Using the reactivity rankings from part (a), the order is W > X > Y > Z. To verify if a reaction is spontaneous, we need to check if the metal with the higher reactivity ranking is found on the left while the metal with lesser reactivity is found on the right. For both reactions: 1. W+ + Y → W + Y+: W (more reactive) + Y (less reactive). This reaction is spontaneous. 2. W+ + Z → W + Z+: W (more reactive) + Z (less reactive). This reaction is also spontaneous. Based on the rankings from part (a), we can confirm that both reactions in part (b) occur spontaneously as written.
