The correct answers : 2. increases; 2. increase.

The rate reaction is depends on the number of factors such as concentration, temperature and catalyst use. The concentration of reactants is one such factors. If the concentration of the reactants doubles, more reactant particles move together, thus collision between reactants increases and the reaction rate is also increased. Therefore, higher the concentration of reactants, the faster the rate of a reaction.
