Red hot carbon will remove oxygen from the oxides XO and YO not from ZO. Y will remove oxygen from XO. Use this evidence to deduce the order of activity of the three metals X, Y and Z putting the most reactive first

Options

  1. AX, Y, Z
  2. BZ, Y, X
  3. CY, X, Z
  4. DZ, X, Y

Correct answer

B. Z, Y, X

Step-by-step solution

Carbon does not reduce ZO and thus, is more reactive. Also Y removes oxygen from XO and thus, Y is more active than X. Thus, activity order is Z, Y, X.
