Choose the substance with the highest vapor pressure at a given temperature. choose the substance with the highest vapor pressure at a given temperature. sis2 sbh3 ch3och2ch3 rbbr bh3

Among the substances that is SiS₂ SbH₃, CH₃OCH₂CH₃ ,RbBr, BH₃;

BH₃ is the one that is having the highest vapor pressure at a given temperature.

As it is the one that is having lowest boiling point and the substance that has lower boiling point will have highest vapour pressure. So, as in here  BH₃, will be having lowest boiling point so it is the one that is having highest vapor pressure.

the answer is true. hope it .
