- The more negative the ∆G of a chemical reaction is, the higher the reaction rate is.
- It is known that the chemical reaction A + B → C + D is a elementary reaction, then it can be inferred that the total order of this reaction is 2.
- If the reaction of 2A+B → C is a elementary reaction, which choice listed below is true? A: it is a second order reaction B: it is a slow reaction C: it is a second order reaction to B D: it is a second order reaction to A
- The energy released by the chemical reaction is ( ) heat.
- Which<br/>of the following reactions can occur in tropane alkaloids?() A: vitali<br/>reaction B: complexation<br/>reaction C: coordination<br/>reaction D: precipitation<br/>reaction E: condensation<br/>reaction
