Answer:
1) Increasing the concentration of HCl [HCl] will increase the reaction rate.
2) The potential energy diagram is shown in the attached image.
3) Because of it is an irreversible reaction that goes to the forward direction . The reaction takes place till HCl dissolves Zn completely.
Explanation:
<em>Q1: State one change in reaction conditions, other than adding catalyst, that will increase the rate of the reaction.</em>
- The rate of the reaction, dissolving Zn in HCl, depends on the concentration of HCl.
Rate = k[HCl]².
<em>Rate ∝ [HCl]².</em>
- The rate is directly proportional to the concentration of HCl raised to the power 2,
<em>So, increasing the concentration of HCl [HCl] will increase the reaction rate.</em>
<em></em>
<em>Q2: Draw a potential energy diagram for this reaction.</em>
<em></em>
- Since the reaction releases energy that appears in the products side. So, the reaction is an exothermic reaction.
In an exothermic reaction, the energy of the reactants is higher than that of the products.
<em>The potential energy diagram is shown in the attached image.</em>
<em></em>
<em>Q3: Explain why this reaction will not reach equilibrium.</em>
Because of it is an irreversible reaction that goes to the forward direction . The reaction takes place till HCl dissolves Zn completely.
