Como parte de un experimento de la clase de ciencia , Janina determinaba cuanto soluto podía disolver en una solución al aumentar la temperatura. Alprincipio comenzo a disolver 50g de soluto a temperatura ambiente de un recipiente con 100ml de agua, pero notó finalmente que el soluto se acumulaba en el fondo del vaso. Procedio a calentar la solucion, lo que le permitio disolver solo 10g adicionalesde soluto

Suppose a pair of chemical compounds a and b can react in two different ways: a + b -> c reaction 1 gives product c. a + b -> d reaction 2 gives product d. the following facts are known about the two reactions: . reaction 1 is endothermic and reaction 2 is exothermic. if a reaction vessel is charged (filled) with a and b , then at first d is produced faster than c. use these facts to sketch a qualitative reaction energy diagram for both reactions. note: because these sketches are only qualitative, the energies don? t have to be exact. they only have to have the right relationship to each other. for example, if one energy is less than another, that fact should be clear in your sketch.
