2. In this experiment you determined the dependence of the reaction rate on the concentration of potassium iodate. Devise an experiment for determining the dependence of the rate on the concentration of sodium sulfite. 3. In this experiment you prepared three graphs using your experimental data. Some of these graphs should have produced straight lines. Explain in terms of the rate law for the reaction why these graphs produced straight lines.

Phase 4: Pricing Strategies and Breakeven Analysis Task: Develop pricing strategies and conduct a breakeven analysis. • Questions to Answer: 1. What is your pricing strategy, and how did you decide on it? 2. What is the breakeven point, considering your estimated fixed and variable costs? • Research Prompt: Explore how companies in your chosen industry typically set their prices. Research average costs for production, marketing, and distribution to make educated guesses for your analysis. • Example for Green Energy Innovations: • Pricing Strategy: Value-based pricing for solar panels at $5,000 each. • Breakeven Point: 50 units to cover fixed costs of $250,000. NACE Competencies Focused: • Critical Thinking • Leadership • Communication Discussion Forum Check-In: • Post: Share your pricing strategy, breakeven analysis, and the assumptions behind your estimates. • Engage: Discuss potential challenges or alternative strategies with at least two peers, focusing on the realism of their guesses.
