Question

1. Explain why food lasts longer when placed in the refrigerator as opposed to on the counter in the kitchen.

2. List and describe four factors that affect the rate of a reaction.

3. Sketch a potential energy diagram for the following reaction: N2(g)+3H2(g)–>2NH3(g)
Use Table I in the Chemistry Reference Table to identify the following on your graph: potential energy of reactants, potential energy of products, activation energy, and heat of reaction. State the value of the enthalpy and whether the reaction is endothermic or exothermic. Label the y-axis and potential energy and x-axis as reaction coordinate.

4. Describe and explain the effect of (a) the increase in temperature, (b) the increase in concentration of C2H4, and (c) a decrease in pressure to the following system at equilibrium: 2C + 2H2 + heat ⇌ C2H4
