PLEASE ANSWER ASAP Marika wants to collect a precipitate of Ca(OH)2. So she makes a 0.01 M
solution of NaOH and mixes it with a 0.05 M solution of Ca(NO3)2. She finds
that the reaction is very slow. What would be the best way to increase the rate
of the reaction?
O A. She could make the original solutions at lower concentrations.
B. She could use less of each solution.
C. She could reduce the temperature of the solutions.
D. She could make the original solutions at higher concentrations.
