How To Calculate Keq Given pKa How To Determine An Unknown Exponent AndreaObzerova/iStock/GettyImages Some chemical reactions are known as reversible reactions because they can go in two directions: forward and reverse. These reactions happen simultaneously and never stop, so they are also called ...
What does A stand for in chemistry? How is it related to molecular complexity? Define the term electrolysis as used in chemistry. What are the characteristics of a substance that determine how it will react with other substances called?
How could you test your gold jewellery to determine whether it is a pure compound or a mixture? What characteristic distinguishes element from compound? Is seawater classified as a mixture or a pure substance? Explain. Is oxygen classified as a mixture or a pure substance? Explain. Describe the...
However, to the best of our knowledge, no relevant quantitative research has been conducted so far to determine the key factors of orchard soil acidification. Lime application is a common measure to restore orchard soil acidification, but the long-term application may lead to soil compaction and ...
the equilibrium shifts to favor the reaction product What are the three steps for a solution to take place? When will a solution be exothermic or endothermic? Define the term heat of solution. Explain how to determine if it is an exothermic or endothermic reaction, and state ...
Determine the equilibrium constant for the following reaction at 655 K: HCN (g) + 2 H2 (g) to CH3NH2 (g) If DeltarH degrees (298.15 K) = -158.0 kJ mol-1; DeltarG degrees (298.15 K) = -92.44 kJ mol-1. Assume the standard reaction enthalpy is independe The ...
c. If Delta G less than 0, then Keq less than 0.1. d. Derive (delta P/delta H)v = -T/V from the fundamental equation for enthalpy. Determine the standard free energy for the reaction below (in kJ) at a temperature of 222 K based on the data given below. 3NO2...
It consists of two electrodes immersed in a solution that used to determine the electric potential generated in the cell. The two electrodes act as cathode and anode. Answer and Explanation:1 It is an electroanalytical sensor that measures the electric potential of ions in an aqueous solution...
What is Keq at 500 K? The change in enthalpy, H of a reaction is found to be 45.3 kJ/mol. This reaction is a) at equilibrium b) exothermic c) spontaneous d) endothermic What is the change in enthalpy of reaction for the...
