The following facts are known about the two reactions: • Reaction 1 is exothermic and Reaction 2 is endothermic. • If a reaction vessel is charged ("filled") with A and B, then at first C is produced faster than D. Use these facts to sketch a qualitative reaction energy diagram for both reactions. Note: because these sketches are only qualitative, the energies don't have to be exact. They only have to have the right relationship to each other. if one energy is less than another, that fact should be clear in your sketch.

I need the answer as soon as possible

Must use dimensional analysis

Answer correctly for temperature and the significant digits please

A marine biologist is preparing a deep-sea submersible for a dive. The sub stores breathing air under high pressure in a spherical air tank that measures 68.0 cm wide. The biologist estimates she will need 8400. L of air for the dive. Calculate the pressure to which this volume of air must be compressed in order to fit into the air tank. Write your answer in atmospheres. Be sure your answer has the correct number of significant digits. 0 atm x10 x Ś

Given the following kinetic parameters, calculate KM. Your numerical answer is assumed to be in units of M. v​0 ​= 2 x 10-​8​ s-​1 ​  Vmax = 1 x 10-​7​ M s-​1​  [S] = 5 mM,

||| Understanding Boyle's Law A cylinder is filled with 10.0 L of gas and a piston is put into it. The initial pressure of the gas is measured to be 166. kPa. The piston is now pulled up, expanding the gas, until the gas has a final volume of 87.0 L. Calculate the final pressure of the gas.

esc An atom of argon has a radius Ir = 71. pm and an average speed in the gas phase at 25°C of 249.m/s. Ar Suppose the speed of an argon atom at 25°C has been measured to within 0.010%. Calculate the smallest possible length of box inside of which the atom could be known to be located with certainty. Write your answer as a multiple of I_ and round it to 2 significant figures. For example, if the smallest box the atom could be in turns r Ar out to be 42.0 times the radius of an atom of argon, you would enter "42.r" as your answer.
