Answer:
1. Heating hydrogen gas from 60°C to 80°C: Entropy increases
2. Subliming dry ice: Entropy increases
3. Forming sucrose crystals from a supersaturated solution: Entropy decreases
4. Condensing water: Entropy decreases
Explanation:
Entropy is a measure of systems disorder. The higher the entropy the higher the disorder. So for the firs example if we heat a gas, molecules move faster, disorder is higher. For second example we are making disordered gas from very ordered crystals also increase in disorder. For 3rd example we are obtaining crystals which brings order. And for the fourth example we make liquid from gas which is also more order.
Answer:An increase in temperature commonly will increase the rate of reaction. An growth in temperature will improve the common kinetic electricity of the reactant molecules.
