Question

For a zero-order reaction, the plot of concentration of reactant versus time is:

(intercept refers to concentration axis)

• A. linear with +ve slope and zero intercept
• B. linear with -ve slope and zero intercept
• C. linear with -ve slope and non-zero intercept
• D. linear with +ve slope and non-zero intercept

Answer 1

The correct option is C linear with -ve slope and non-zero intercept

$a=a_o-kt⟶$ zero order

So a us $T$ a straight line of $-ve$ slope with non zero intercept $a_o.$
