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

A

t=[R0]kt = \frac{\lbrack R_{0}\rbrack}{k}

B

t=[R]−[R0]t = \lbrack R\rbrack - \lbrack R_{0}\rbrack

C

t=k[R0]t = \frac{k}{\lbrack R_{0}\rbrack}

D

t=[R0]−[R][R0]t = \frac{\lbrack R_{0}\rbrack - \lbrack R\rbrack}{\lbrack R_{0}\rbrack}

Answer

t=[R0]kt = \frac{\lbrack R_{0}\rbrack}{k}

Explanation

Solution

[R]=[R0]−kt\lbrack R\rbrack = \lbrack R_{0}\rbrack - kt

For a completion of reaction [R] = 0

Or t=[R0]kt = \frac{\lbrack R_{0}\rbrack}{k}
