State whether it be worthwhile to investigate finding a catalyst to use in this reaction under standard conditions and explain why. a.)yes, because is negative. b.)no, because is negative. c.)yes, because is positive. d.)no, because is positive.

Option A (Yes, because ΔG is negative)

Explanation:

- ΔG depicts that the reaction will be occurring naturally  

A catalyst is used to increase the rate of a reaction by lowering the activation energy  and is not involved in the reaction chemically as it does not get consumed in the process  

Catalyst is used in those reaction where the rate of reaction is slower than we want it to be, where ΔG is negative.

A good example of a catalyst is Vanadium pentaoxide ( V2O5) that is used in contact process (Production of Sulphuric Acid), here V2O5 is used to speed up the reaction because the reaction is process is slower in general.

considering the question as per the attachment

here we can see that the radon nuclide has 222 as the atomic mass number and 86 as the atomic number.

when it undergoes nuclear fission it gives polonium which has atomic mass number as 218 and atomic number will be 84 along with a helium nucleus which has 4 atomic mass number and 2 as its atomic number.

222 = 218 + 4 (atomic mass number)

86 = ? + 2; therefore ? = 86-2 = 84.

the atomic mass number of polonium will be 84.
