According to le chatelier's principle, by increasing the temperature of the system shown below, the equilibrium will shift to the right (towards products).a b imported asset heat ab. is that true?

The statement for the said principle is "If a dynamic equilibrium is disturbed by changing the conditions, the position of equilibrium moves to counteract the change." If the reaction gives off energy or is exothermic then the statement will be false however when the reaction absorbs energy or is endothermic then the statement will be true.

Ithink the answer is a or d.

Ch4 and ph3 are both covalent since they are composed both of non-metals.    ch4 is non- polar because of  london forces and has a geometry of tetrahedral  ph3 , on the other hand, is umbrella shaped polar and has dipole-dipole intermolecular force (imf) . since ph3 is polar, it has a stronger imf
