Question

For a zero order reaction, the plot of concentration of reactant reacted vs time is linear with:

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

Answer 1

The correct option is A $+ve$ slope and zero intercept

As we know,

For zero order

$rate=k[A{]}^0$

$a-(a-x)=kt$

From the above derivation for the reactant reacted equation rearranged to:

$x=k^{\prime }t$

$\therefore Slope=+ve$

Intercept $=$ Zero
