For the reaction as shown in the bellow figure, the rate of formation of Z is 0.2 gm mole/litre.hr. What is the rate of disappearance of X in gm mole/litre.hr ?
Correct answer: A
Explanation
Based on the stoichiometry (2X -> Z + Y), twice as much X is consumed as Z is formed. Thus, rate of disappearance of X = 2 * rate of formation of Z.
