I need help in my homework **Equilibrium: Data Sheet****Fill in the following table:**| Test Tube | Substance Added / Temperature Change | Color Trial 1 | Color Trial 2 ||-----------|-------------------------------------|---------------|---------------|| 1 | 10 drops water | Reference color: | - || 2 | 8 drops Fe (NO₃)₂ | Dark Red | Dark Red || 3 | 8 drops KSCN | Dark Red | Dark Red || 4 | 8 drops HCl | Light Orange | Light Orange || 5 | 10 drops H₂O + Heat | Light Orange | Light Orange || 6 | 10 drops H₂O + Cold | Dark Red | Dark Orange Red |This data sheet is used to record color changes as different substances or conditions (such as temperature changes) are applied to solutions in test tubes. Each test tube contains a specific combination of substances and the resulting color is noted for two trials. # Equilibrium Shift in Chemical Reactions## Experiment OverviewThis educational content examines the shift in chemical equilibrium using the following reaction:\[ \text{Fe}^{3+} (\text{aq}) + \text{SCN}^- (\text{aq}) \rightleftharpoons \text{FeSCN}^{2+} (\text{aq}) \]The direction of the equilibrium shift is observed in response to various stresses applied to the system. Understanding how equilibrium responds to changes is essential in predicting the behavior of chemical systems.## Experiment Data Table| Test Tube | Direction of Shift | Type of Stress (e.g., reactant added, product removed, temperature increase) | Explanation of Shift ||-----------|------------------------|----------------------------------------------------------------------------|---------------------|| 2 | Forward Reaction | | || 3 | Forward Reaction | | || 4 | Backward Reaction | | || 5 | Backward Reaction | | || 6 | Forward Reaction | | |### Explanation- **Forward Reaction**: This indicates a shift towards forming more products (FeSCN²⁺).- **Backward Reaction**: This indicates a shift towards forming more reactants (Fe³⁺ and SCN⁻).### Understanding Equilibrium Shift1. **Le Chatelier's Principle**: When a system at equilibrium is disturbed, it will adjust to minimize the disturbance.2. **Application of Stresses**: - Addition of a reactant or removal of a product typically shifts the equilibrium towards the forward reaction. - Addition of a product or removal of a reactant typically shifts the equilibrium towards the backward reaction. - Changes in temperature or pressure can also affect the equilibrium direction.By applying these principles, students can predict and explain the behavior of chemical systems in response to various conditions.This table serves as a guide for interpreting shifts in chemical equilibrium, crucial for studies in chemistry and related fields.

According to the Le Chatelier's principle when a stress is applied, the equilibrium will reposition itself and shift in opposite direction to that of applied stress. This stress could be change in temperature, pressure, moles of gaseous products, concentration or heat of the reaction.Test tube direction of shift Type of stress Explain how direction of shift will relieve the applied stress 2 Forward reaction Increasing Fe3+ concentration (reactant concentration) By adding Fe(NO3)2 the reactant concentration increases so the stress applied is on left side and to balance this the equilibrium will shift right (forward) to increase more product formation. 3 Forward reaction Increasing SCN- concentration By adding KSCN, the reactant concentration will increase, hence the equilibrium will move forward 4 Backward reaction More product The chloride ions will combine with Iron ion to form some product that is insoluble, therefore the equilibrium will more reactants and so it will shift backward 5 Backward reaction Addition of heat/ Temperature increase Adding heat will drive the reaction forward, increasing the product formation so to balance this out the equilibrium will shift bacwards. 6 Forward reaction Temperature is decreased If temperature is decreased the reactants do not react actively, and the product formation will slow down and hence to balance this out the equilibrium shifts forward towards more product formation.
