A) positive slope and zero intercept
B) positive slope and non zero intercept
C) negative slope and zero intercept
D) negative slope and non zero intercept
Correct Answer: D
Solution :
For a first-order reaction, the rate expression is \[\log \left\{ {{[A]}_{t}}M \right\}-\log \left\{ {{[A]}_{0}}M \right\}=-\left\{ kt/2.303 \right\}.\] Thus, the plot of \[\log \left\{ {{[A]}_{t}}/M \right\}\]versus t is linear with a negative slope \[\left( -\frac{k}{2.303} \right)\] and non zero intercept.You need to login to perform this action.
