1. To observe the effect of temperature on reaction rate, the reaction between KMnO₄ and H₂C₂O₄ in acidic media is performed according to the given redox reaction,

                     2MnO₄^- + 16H⁺ + 5(C₂O₄)^2- → 10CO₂ + 2 Mn²⁺ + 8 H₂O

In the experiment, 4 mL 5x10^-3 M H₂C₂O₄ is added to the test tube containing 5 mL of 3x10^-4 M KMnO₄ and 1 mL of 0.25 M H₂SO₄ solutions, at 45⁰C.

1. Write expressions for the rate of the reaction in terms of the reactants and products (stoichiometric rate equation)
2. Which reactant is the limiting compound? Explain why?
3. If the reaction is completed in 60 s at 45°C, calculate the reaction rate
4. Explain the possible effect of temperature on the reaction rate by using the Arrhenius equation.

Is the thickness of an annual layer of ice smallest at the top or bottom of the core? Why? And why is this important to acknowledge?

explain why the ice age and gas ages are different.

If 7.45 g of N2 and 4.20 g of O2 react according to: 2 N2(g) + O2(g) → 2 N2O(g)

a) Which reactant is in excess?

b) Calculate the mass of product formed.

3. Arcylonitrile, C3H3N, is the starting material for the production of a kind of synthetic fibre. It can be made from propylene, C3H6, by reaction with nitric oxide, NO, as follows: 4 C3H6(s) + 6 NO(g) → 4 C3H3N(s) + 6 H2O(l) + N2(g)

What mass of C3H3N can be made when 21.6 g of C3H6 react with 21.6 g of nitric oxide? Identify the limiting reactant in the reaction.

Assignment 3

Procedural Text: Database Search

A process for the production of 1,3-butadiene results from the catalytic dehydrogenation at atmospheric pressure of 1-butene according to the reaction

C4H8(g) C4H6(g) + H2(g)

To suppress side reactions, the 1-butene feed stream is diluted with steam in the ratio of 10 moles of steam per mole of 1-butene. The reaction is carried out isothermally at 525oC, and at this temperature 33% of the 1-butene is converted to 1,3-butadiene. How much heat is transferred to the reactor per mole of entering 1- butene?

Describe an ecosystem that you are familiar with. Include examples of abiotic and biotic factors, producers, consumers, and decomposers. Describe at least two ways that humans have impacted this ecosystem, or similar ecosystems. What is the effect on biodiversity?

Reactant A decomposes by three simultaneous reactions to form three products, one that is desired, B, and two that are undesired, X and Y. These gas-phase reactions, along with the rate laws, are as follows. (40pts) 1) A→X -r1A = rX= k1 = 0.0001 mol dm-3 sec-1 2) A→B -r2A = rB = k2 CA 2 = (0.0015 s-1 ) CA 2 3) A→Y -r3A=rY=k3 = 0.008 dm3 mol-1 sec-1 The specific reaction rates are given at 300 K and the activation energies for reactions (1), (2), and (3) are E1 = 10,000 kcal/mole, E2 = 12,000 kcal/mole, and E3 = 20,000 kcal/mole. (a) How, and under what conditions (e.g., reactor type(s), temperature, concentrations), should the reaction be carried out to maximize the selectivity of species B for an entering concentration of species A of 0.4 M and a volumetric flow rate of 2.0 dm3 /s? (b) Design the suitable type of reactor assuming there is no pressure drop.
