Determine right or wrong (format for answering: Wrong Right Wrong Right Wrong Right Right Wrong Wrong) 1. The main way to improve the evaporation capacity of an evaporator is to increase its heat transfer coefficient. 2. The purity of the gases participating in the reaction affects both the reduction temperature and rate of the catalyst. 3. Generally, 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. Instead, it merely reflects the sensitivity of the reaction rate to the concentration of the reactants. 4. According to national standards, standard solutions used in titrimetric analysis should generally not be used for more than two months at room temperature (15–25°C); otherwise, their concentration must be recalibrated. 5. The corrosion of carbon steel in strong acids and strong bases is uniform corrosion. 6. When an oval manhole is provided on an internally pressurized cylinder, its long axis should be aligned with the longitudinal direction. 7. Scaling on the working surface of tower equipment usually occurs in the dead corners of the structure. 8. It is not allowed to gently tap the gauge casing with the hand while calibrating it. 9. When measuring flow rate using a throttle orifice plate, the smaller the flow rate, the smaller the measurement error. 10. The unit of force, N (Newton), is a fundamental unit in the International System of Units. Reference answer: Right Wrong Right Right Right Wrong Right Wrong Wrong Wrong.
