Correct answer
90
Step-by-step explanation
From the given graph, the plot of half-life versus initial concentration is a straight line passing through the origin.
This indicates that is directly proportional to , which means .
Therefore, the ratio is constant.
Using the coordinates from the graph, we get:
Solving for :
The value of is .
