What is the half life of a first order reaction if it takes 4.4 x 10-2 seconds for the concentration to decrease from an initial concentration
A certain second-order reaction (B-> Products) has a rate constant of 1.80×10^-3 M^-1xs^-1 at 27C and an initial half-life of 216 s . What is the concentration of the reactant B after one half-life?Express the molar concentration numerically.
A gas expands and does P-V work on the surroundings equal to 281 J. At the same time, it absorbs 216 J of heat from the surroundings. What is the change in energy of the system?
