)for a certain reaction, kc=0.514 and kf=38.2 m^-2 x s^-1 . calculate the value of the reverse rate constant, kr, given that the reverse reaction is of the same molecularity as the forward reaction.
express your answer with the appropriate units.

part b)

for a different reaction, kc=1.28×10^3 , kf=1.77×10^3 s^-1 , and kr=1.38 s^-1 . adding a catalyst increases the forward rate constant to 7.47×10^5 s^-1. what is the new value of the reverse reaction constant, k_r, after adding catalyst?
express your answer with the appropriate units.

What is the molarity of a solution that is prepared by adding 57.1 g of toluene (c 7 h 8 ) (density = 0.867 g/ml) to a 250 ml volumetric flask, and then filling to the mark with benzene (c 6 h 6 ) (density = 0.876 g/ml)?

The speed of light is around 6.706×10^8 miles per hour. what is the speed of light in units of miles per minute?

Microtubular fibers that assist in the movement of chromosomes during nuclear division in conjunction with proteins, makes up the small and large organelle pieces that assemble prior to translation three-base nucleotide sequence that can complementarily pair with the functional transcript, allowing a particular material to be brought to a ribosome particular time in the cell cycle when the cell’s systems determine if the cellular conditions are appropriate to continue through the cycle time in the cell’s cycle when proteins are made and organelles are duplicated enzyme that allows proper nucleotide bonding during transcription specific dna sequence which will initiate gene transcription division of the cell’s cytoplasm specific bond that forms between two amino acids when a carboxyl group binds to a amino group three-base sequence that does not code for a particular amino acid a paired organelle which facilitates the formation of movement microtubules time in the cell’s cycle when the microtubular structures exert an equal pressure on the cell’s genetic material
