Mass Transfer The feed to fractionating column is changed from saturated vapour to saturated liquid. If the separation and reflux ratio remains unchanged, the number of ideal stages will Increase Remains same Depend on saturated boiling point; may increase or decrease Decrease Increase Remains same Depend on saturated boiling point; may increase or decrease Decrease ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer In extraction, as the temperature increases, the area of hetrogeneity (area covered by binodal curve) Remains unchanged Decreases Increases None of these Remains unchanged Decreases Increases None of these ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer Steam distillation is not recommended to be used, if the Azeotropic mixture is to be separated and the final product is miscible with water Material can not be distilled by indirect heating even under low pressure, because of the high boiling temperature Material to be distilled is thermally unstable or has the tendency to react with other components associated with it, at the boiling temperature Liquids decompose, if distilled directly at atmospheric pressure Azeotropic mixture is to be separated and the final product is miscible with water Material can not be distilled by indirect heating even under low pressure, because of the high boiling temperature Material to be distilled is thermally unstable or has the tendency to react with other components associated with it, at the boiling temperature Liquids decompose, if distilled directly at atmospheric pressure ANSWER DOWNLOAD EXAMIANS APP
