The rate of effusion for water and hydrogen sulfide is 1.375.
To determine the rate of effusion for a gas, you can use Graham's Law
So, the rate of effusion of a gas is proportional to
In your case, you have to determine the ratio between the effusion rate of water and the ffusion rate of hydrogen sulfide. Using Graham's Law, you can write
This means that you get
In other words, water has a faster effusion rate than hydrogen sulfide.
