observing initial rates

Why is it easier to observe initial rates when t is close to t=0

This is because by definition, initial rates refer to the rate of the forward reaction at the moment it has started. Mathematically, this is when t approaches 0.

t=0 usually is the start for most reactions so when you are wanting to observe initial rates you want to observe rates that are closest to zero. It can be initial rates right after time t=0 so it is easiest to measure.

It is good to measure at close to t=0 because there will only be reactants present and no products formed. If there are products present then there is a high chance that the reverse reaction is occurring simultaneously so it will be hard to determine the rate.
