The decomposition of formic acid follows first-order kinetics.
HCO2H(g) → CO2(g) + H2(g) The half-life for the reaction at 550°C
is 24 seconds. How many seconds does it take for the formic acid
concentration to decrease by 87.5%?
7 / 13 100% + prod Reaction path 43. The decomposition of formic acid follows first-order kinetics. HCO,H(g) — COz(g)+Hz(g) The half-life for the reaction at 550°C is 24 seconds. How many seconds does it take for the formic acid concentration to decrease by 87.5%? A) 24 s B) 0.042 s C) 4.6 s D) 48.8 s E) 12.2 s 44. For the second-order reaction below, the initial concentration of A is 1.00 M. If the concentration of A is reduced to 0.43 M after 75 seconds, what is the rate constant? rate = k [A]² 2A → B B) 5.7 x 103 L/mol.s A) 5.2 x 10 L/mol.s C) 7.6 x 103 L/mol D) 1,1 x 102 L/mol-s E) 1.8x 102 L/mol.s Which of the following statemente recording the equilibrium constant in norment? 99+ OF
