Which of the following methods will usually cause a reaction to speed up? Combining the reactants at a lower temperature. Reducing the concentration of reactants. Grinding one of the reactants into a powder. Removing the catalyst.

Ans: grinding one of the reactants into a powder.

this increases the surface area and hence there would be more chances of collisions happening. therefore reaction rate would increase

The action can speed up the rate of a chemical reaction by grinding one of the reactants into a powder.

What is the rate of reaction?

The Rate of a chemical reaction tells about the duration of time at which reaction is complete.

The Rate of reaction is also defined as the rate of change of concentration of reactant with respect to the time. So, concentration of reactant is directly proportional to the rate of a reaction and wherever we increase the surface area of reactant rate increases as reactant will participate through large possible sides. Catalyst also speeds up the reaction without being involved in it and high temperature also increases the kinetic energy of the reactant to do effective collision.

Hence, option C is correct i.e. Grinding one of the reactants into a powder.
