Given the following reaction at 298 K:
ATP(aq) + H2O(l) → ADP(aq) + Pi(aq) ΔG∘rxn = -30.5 kJ

In a particular cell, the concentrations of ATP, ADP, and Pi are 3.6×10−3 M , 1.2×10−3 M , and 5.1×10−3 M , respectively. Calculate the free energy change for the hydrolysis of ATP under these conditions. (Assume a temperature of 298 K.)

Butadiene undergoes a reaction at a certain temperature in the gas phase as follows: 2c4h6(g) --> c8h12(g) the following data were collected for this reaction: time (min) [c4h6] (m) 0 0.36 15 0.30 30 0.25 48 0.19 75 0. determine the order of the reaction and the rate constant. 1st order and k = 4.3x10 -4 s-1 1st order and k = 2.3x10-4 s-1 2nd order and k = 4.3x10-4 s-1 2nd order and k = 2.3x10-4 s-1 zero and k = 4.3x10-4 s-1
