For a chemical reaction `2X + Y rarrZ`, the rate of appearance of `Z` is `0.05 mol L^(-1) min^(-1)`. The rate of diappearance of `X` will beA. `0.05 mol L^(-1) hr^(-1)`B. `0.05 mol L^(-1) min^(-1)`C. `0.1 mol L^(-1) min^(-1)`D. `0.25 mol L^(-1) min^(-1)`

Answer» Correct Answer - C
`2X+Y rarr Z`
Rate `= (-d[X])/(2 dt) =(-d[Y])/(dt) = (+d[Z])/(dt)`
`:. (-d[X])/(dt) = 2 xx (d[Z])/(dt) = 2 xx 0.05 = 0.1 mol L^(-1) min^(-1)`Correct Answer - C
`2X+Y rarr Z`
Rate `= (-d[X])/(2 dt) =(-d[Y])/(dt) = (+d[Z])/(dt)`
`:. (-d[X])/(dt) = 2 xx (d[Z])/(dt) = 2 xx 0.05 = 0.1 mol L^(-1) min^(-1)`
