Answer #1
a larger value of ΔG‡ for the reaction: It will result in slower rate as more the negative value of free energy change more the spontaneity of reaction
a greater number of collisions between reacting molecules in a given period of time: More the collision more the rate of reaction
a larger fraction of collisions that occur with the proper orientation for reaction: More the effective collision more the rate of reaction
a more stable transition state: More the stability of transition state more the rate of reaction

So answer is a larger value of ΔG‡ for the reaction
