Nickel forms a gaseous compound of the formula Ni(CO)x.The value of x given that under the same conditions of temperature and pressure methane effuses 3.25 times faster than the compound is _____(answer should be an integer). (Given : Ni = 58.7)Correct answer is '6'. Can you explain this answer?

Question

Answer

Solution:

Effusion rate is inversely proportional to the square root of molar mass.

For methane, effusion rate (r) is given as:

r = 1/√(16)

For Ni(CO)x, effusion rate (r') is given as:

r' = 1/√(58.7 + 12 +16x)

The ratio of effusion rates is given as:

r/r' = 3.25

Substituting the values of r, r' and solving for x, we get:

x = 6

Therefore, the value of x for the gaseous compound Ni(CO)x is 6.
