In accordance with the forum’s uniform requirements, the maximum score for this activity is 15 Wealth points; giving scores based on charm is prohibited. Friendships and duplicate ratings are also declined. To encourage active participation from members, full marks are given for all correct answers, while 10–12 wealth points are deducted for each incorrect answer. 2 mistakes result in 8–10 wealth points; the rest receive encouragement points of 4–6 wealth points for their participation. 1. Under normal circumstances, the reaction order remains constant within a certain temperature range. The value of the reaction order does not alone determine the speed of the reaction; it merely reflects the sensitivity of the reaction rate to concentration. 2. According to national standards, standard solutions used in titrimetric analysis should generally have a shelf life of no more than two months at room temperature (15–25°C); otherwise, their concentration must be recalibrated. 3. The corrosion of carbon steel in strong acids and strong bases is a type of uniform corrosion. 4. When creating an oval manhole in an internally pressurized cylinder, its long axis should be aligned with the longitudinal direction. 5. Scaling on the working surfaces of tower equipment usually occurs in the dead zones of the structure. 6. It is not allowed to gently tap the gauge casing with the hand while calibrating it. 7. When using a throttle orifice plate to measure flow rate, the smaller the flow rate, the smaller the measurement error. 8. In the International System of Units, the unit of force, N (Newton), is a base unit. 9. Increasing the temperature certainly speeds up the reaction rate, but it does not necessarily increase the conversion rate of the reactants. 10. Vinegar can help people who have drunk too much sober up, as vinegar and alcohol can undergo an esterification reaction. Answer: Right right right wrong right Wrong wrong wrong right.
