There are two reaction vessels, one containing A and the other containing B, with equal concentrations at t=0. If both substances decompose by first order kinetics, where kA = 4.70 × 10⁻⁴ s⁻¹ kB = 3.2 × 10⁻³ how much time must pass to reach a condition where [A] = 3.05[B]?

29.1-12=17.1the answer is this one

Firstly, the water in the dams hold gravitational potential energy as they are above ground level. the gravitational potential energy is then transferred to kinetic energy as it falls, spinning the turbinethe turbine then spins the generator, which is a large magnet surrounded by metal coils. by doing this, the generator generates electricity. in this action, the energy transfer taken place is kinetic to electric energy
