As the elements of group 16 (via) are considered from top to bottom on the periodic table, the atomic radii

In a reaction (at equilibrium) that makes more moles of gas than it consumes, what is the effect of increasing the pressure?

Precision can be defined as the o exact center of a data set. o reproducibility of a measured value. o correlation between two variables that are measured in a data set agreement between a measured value and an accepted value.

Iwould appreciate if someone could me.
