Please answer questions 1 and 2 on The rate constant for the reaction answered A + B->C out of 1.0 is 4.1 x104 U(mol s) at 593 K. The activation energy is 101 kj/mol. question Determine the temperature when the rate constant is 1.2 x10-3 L/(mol s)- Answer: 2 One (often inaccurate) rule of thumb in biology is that a 10 °C change increases the rate by a factor of ten. If the lower temperature is 3 °C, what activation...

Enter your answer in the provided box. Given two complementary strands of DNA containing 1.01 X 102 base pairs each, calculate the ratio of two separate strands to hydrogen-bonded double helix in solution at 3.49 x 10² K. (Hint: The formula for calculating this ratio is e-SE/RT, where AE is the energy difference between hydrogen-bonded double-strand DNAs and single-strand DNAs and R is the gas constant.) Assume the energy of hydrogen bonds per base pair to be 7.70 x 102...
