Determine the enthalpy of adsorption for the reaction of hydrogen gas adsorbing onto a platinum surface, given that 2.00 g of hydrogen gas is adsorbed onto a 1.00 g platinum surface at 25°C and the pressure is 1 bar. The volume of the system is 1.00 L and the initial temperature of the platinum surface is also 25°C. Assume that the surface is in thermal equilibrium with the surroundings and that the gas behaves ideally.

Here's a specific problem related to DNA-protein interactions and regulation for a chemistry student to solve:How does the binding affinity of a transcription factor to DNA affect gene expression? Investigate the factors that influence this interaction using experimental data and molecular modeling techniques. Specifically, determine how changes in concentration, temperature, pH, and DNA sequence impact the stability and specificity of the protein-DNA complex. Based on your findings, propose potential strategies for regulating gene expression through targeted modulation of transcription factor-DNA interactions.
