Dalton b. Thomson c. Bohr d. Rutherford 6) Which of the following rate laws is a fourth-order reaction? a. r = k[X][Y]²[Z] b._r= k[X]²[Y]³ C. r = k[X][Y]² d._r= k[X][Y]²[Z]ª 7) The activation energy of a particular reaction will decrease if: a. A catalyst is used. b. Temperature is increased. c. Reactant concentration is increased. d. All of the abovearrow_forward
- pls helparrow_forwardState the reason why compound A (m.p. 99-100°C) is heated under vacuum.1. So that the sample heating temperature is not too high when heated under vacuum.2. So that the temperature is higher than the melting point of compound A.3. So that cold water is not required in the sublimator.arrow_forwardTo find the theoretical % yield of a given reaction:1. actual amount obtained once crystallized2. (actual amount obtained / theoretical amount) x 1003. maximum amount of product that can be obtained / amount of initial reactantarrow_forward
- The reason activated carbon decolorizes and purifies a product is:1. It helps dissolve the product and then recrystallize it.2. It reacts with impurities in the product and removes them.3. It retains impurities by adsorption, purifying the product.arrow_forwardThe principle of a rotary evaporator is the same as that of:1. vacuum distillation2. reflux3. fractional distillationarrow_forwardAnhydrous MgSO4 is used to:1. Form a salt with the compound dissolved in the solution2. Remove water from a solution3. Neutralize a solutionarrow_forward
