Kinetic energy is the energy possessed by a moving object KE = 1/2 mv^2

m = mass (kg)
v = velocity (m/s)
KE = Kinetic energy (J)

Solve the numerical problem about the kinetic energy by using the formula above
(with working)​

The first-order reaction a→2b+c has rate constant 0.538 s−1. if the initial concentration of a is 0.867 mol l−1, what is the half-life of the reaction in seconds? remember to use correct significant figures in your answer (round your answer to the nearest hundredth). do not include units in your response.
