Can a Minimum Possible Efficiency be proven?

Given a problem, is it possible to prove what the best worst-case efficiency of an algorithm to solve this problem would be? For example, lets take the problem of sorting an array. … Many of the simpler sort algorithms have a worst-case efficiency of $O(n^2)$ such as Quick Sort and Bubble Sort. …
