Sabemos que, en la Tierra, sobre cualquier cuerpo en reposo, actúa siempre al menos una fuerza, la gravitatoria. ¿Por qué entonces, no se mueve?

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.
