Kinetics P1 questions

[allthebest]

I attached the questions in the images below. I think the answers are wrong. Are they correct or am I correct?

My answers:

1. B 2

2. A  A:1, B:1

3. A  A:1, B:1

The answer from the pdf:

1. D

2. D

3. B

I'm confused because of their answers since it's different from what I learned. Please help me clarify

Thank you in advance

I would just double check if the answer key is of the same version as the questions/textbook, and if you are looking at the right answer key. Otherwise I agree with your answers over the key.
