Most effects can be categorized by whether they modify a signal in time, in frequency, or some blend of the two. Reverb is predominantly a time domain effect while equalization is almost purely frequency domain. You can't really fake one with the other.

Reverb and delay are pretty closely related, however, so you could get a reverb-like effect with a delay and vice-versa.

Again, I encourage you to grab a book or take a course on audio production. You'd probably really enjoy it.
