True and False...

1. A thermodynamically favorable reaction also proceeds spontaneously.
I think that it is false?

2. Doubling the concentration of a reactant always causes the reaction rate to double.

3. a reaction that has a large activation energy in the forward direction direction will also have a large activation energy in the reverse.
I think this one will be false too....?

4. A reaction is favorable if the free energy change is negative...... true?

I think 1 is true.
2 is true in most cases but not in all; therefore, I would vote for false. (There are some reactions [zero order] where the concentration is not a factor. See (Broken Link Removed)
I think you are right for 3.
4 is true
