Question

For the reaction \[\ce{A + 2B -> C}\], the instantaneous rate of reaction at a given instant can be represented by ____________.

विकल्प

• `+("d"["A"])/"dt" = + 1/2 ("d"["B"])/"dt" = + ("d"["C"])/"dt"`

• `("d"["A"])/"dt" = (2"d"["B"])/"dt" = - ("d"["C"])/"dt"`

• `-("d"["A"])/"dt" = -1/2 ("d"["B"])/"dt" = + ("d"["C"])/"dt"`

• `+("d"["A"])/"dt" = +1/2 ("d"["B"])/"dt" = -("d"["C"])/"dt"`

Answer 1

For the reaction \[\ce{A + 2B -> C}\], the instantaneous rate of reaction at a given instant can be represented by `underline(-("d"["A"])/"dt" = -1/2 ("d"["B"])/"dt" = + ("d"["C"])/"dt")`.

Explanation:

In a balanced chemical equation, the instantaneous rate of reaction is equal to the instantaneous rate of consumption of a reactant or the instantaneous rate of production of a product divided by its coefficient.
