Question
In the reaction: N2 + 3H2 rightarrow 2 NH3 + heat, describe in LeChatelier's terminology two ways to favor the product side of the reaction. Also, is this reaction exothermic or endothermic? Explain how an increase in temperature, catalyst and concentration of reactants increases the reaction. Use the activation energy term in part of your explanations. What is the simplest formula for a compound with the following mole ratios? 0.300 mole K and 0.100 mole P 0.200 mole CuSO4 and 1.00 mole H2O When 5.00 g of copper reacts with oxygen, the copper oxide product has a mass of 5.62g. What is the empirical formula of this copper oxide? MM Cu = 63.5, O = 16.0 Explain why KBr dissolves in water but not in cooking oil. KBr dissolves is water and not cooking oil because A 20.00 ml. sample of NaCl solution has a mass of 20.75g. After the NaCl solution is evaporated to dryness the dry salt has a mass of 4.35g. Calculate the following concentration for the NaCl solution, MM NaCl = 58.5 % m/m (or % w/w) % m/v Molarity (M) What is the molarity of acetic acid, CH3COOH (MM = 60.0) in vinegar requires 22.50 mL of a 0.195 M NaOH solution to neutralize it?Explanation / Answer
9. Add moles of either N2 or H2, it will favour product side. It is exothermic reaction.
10. If you increase reactant, reaction rate will increase and more of product will be formed. On increasing catalyst activation energy will decrease and reaction rate will increase.
11. A) K3P
B) (CuSO4)2. H2O
15. M1
