Step-by-step solution

2 steps

  1. Identify factors that increase the rate of reaction.

    For the reaction between a solid and a liquid, several factors can increase the reaction rate. These include increasing the concentration of the aqueous reactant, increasing the temperature, and increasing the surface area of the solid reactant.

  2. State two ways to increase the reaction rate for CuCO3(s)+2HCl(aq)→CuCl2(aq)+H2O(l)+CO2(g)\text{CuCO}_3(\text{s}) + 2\text{HCl}(\text{aq}) \to \text{CuCl}_2(\text{aq}) + \text{H}_2\text{O}(\text{l}) + \text{CO}_2(\text{g}).

    • Increase the concentration of the hydrochloric acid.
    • Increase the temperature of the reaction mixture.
    • Increase the surface area of the copper(II) carbonate (e.g., by using it in powdered form instead of lumps).

    I will choose two from these.

    The rate of the reaction can be increased by:

    1. Increasing the concentration of the hydrochloric acid.
    2. Increasing the temperature of the reaction.
