Question

The expression to calculate time required for completion of zero order reaction is ______.

Options

• t = `(["R"_0])/"k"`

• t = [R] - [R₀]

• t = `"k"/(["R"_0])`

• t = `(["R"_0] - ["R"])/(["R"_0])`

Answer 1

The expression to calculate time required for completion of zero order reaction is `underline("t" = (["R"_0])/"k")`.

Explanation:

For zero order reaction,

[R] = [R]₀ - kt

for completion of reaction,

[R] = 0, t = `(["R"_0])/"k"`
