In the reaction, A → Products, the rate constant is 7.5 × 10−3 M−1 s−1.

If the initial concentration of A is 0.613 M, what will be the concentration of A (in M) at t = 11.5 s?

Only enter the numerical value with three significant figures in the answer box below. Do NOT type in the unit (M).

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.

consider the reaction below.
