It's not enough time. You need two hours, minimum. But if you do not have any checked bags, you might make it.
The problem will be your checked bag(s). Sometimes the bags come off the belt very quickly, but I have also waited 45-60 minutes for my bag.
The other problem is that when your bag is re-checked, it goes through the same TSA BS as if you just checked in for your first segment. And ORD TSA has proven many times that they cannot handle the load.
Even on flights from YYZ (where you clear ICE in YYZ), they still send your bag through the CTX machine before it's shipped off to your connection.
Ergo, there's a chance YOU might make it, but your bag won't. Happens a lot.
