GATE BT2017 Answer Key  Solutions Discussion

Infact the formula used is....A0A=kt
Where A0 has the unit moles....A is final conc which is zero.

Similarly, k is expected to have units in M per sec or min (or moles per litre per min)

Similarly, k is expected to have units in M per sec or min (or moles per litre per min)
But d formula that can fit is A0A=kt
Where A is in moles nd k in moles/min?
If so....the answer will be 10000
So this can be challenged...right?
Sunil sir plz help me wid question no. 16 also.

Right Bro. It should have been either in grams/milligrams(i.e  mg/min) or M(molarity). Fell for the same trap. I thought, I was the only one.
If someone challenges it, gets it right will everyone with that answer be awarded.
What about that plasmid question. There is no xho1 site in MCS or any part of plasmid?

This question can simply be challenged on the basis of unitary approach, supported by the fact that unit of k leads to imbalance of units on reactant n product sides (if one tries to follow the approach used for obtaining 100 mins as solution).
