True or False: 1. The initial concentration of an intermediate is assumed as 0 when using steady-state approximation. 2. A spontaneous reaction with ΔG = -1070 J/mol happens at 562 K, the Keq of this process is less than 1.
The following are Biophysical Chemistry Questions: When we are determining the equilibrium affinity (K) for a binding reaction or the rate constant (k) for a reaction, why do we make multiple measurements? Why is it useful to put one (or more) reagents in great excess of the other (for equilibrium analysis or kinetic analysis?) Why do you start learning about heat and work in thermodynamics witht the ideal gases instead of chemical reactions?
help me here please, this is my last attempt. Thanks!

Imagine that a few tenths of a mole of each compound is dissolved in a liter of water. Then, write down in the third column of the table the chemical formula of the major chemical species that will be present in this solution. For example, you know water itself will be present, so you can begin each list with the chemical formula for water (H₂O).

12:27 12-2 Analyzing Data... NAME Energy (kJ) NAME 1000 Many chemical reactions involve a change in energy. When the energy of the reactants is greater than the energy of the products, the reaction gives off heat and is exothermic. When the energy of the products is greater than that of the reactants, the reaction must absorb energy from the surroundings to occur and is endothermic. If the intermediate stage (the activated complex) is of a higher energy, then the reaction can only take place if the reactants are given an initial energy input (the activation energy). The graph shows energy diagrams that indicate how the energy changes as three reactions occur.
