1. How is the rate affected by doubling the concentratino?

2. Explain the effect of concentration on the rate of a reaction in terms of the "Collision Theory" of chemical reactions.

3. Considering that 1/Time is proportional to the rate of the reaction how is the rate of the reactions affected by concentration?

    1. Generally, the rate is doubled IF the reaction is a first order in that constituent but the problem doesn't state that. About the only thing you can say, and that isn't certain, is that the rate is increased. It will be doubled if the reaction is first order in that substance, quadrupled if second order, etc.
    2. More molecules in the same volume mean more collisions per unit time and that means a faster rate of reaction.
    3. I pass on 3.
