Catalyst is a substance which accelerates the rate of a chemical reaction without undergoing any change in its chemical composition or mass during the reaction. The phenomenon of increasing the rate of a reaction with the help of a catalyst is known as catalysis.
Relative humidity is the ratio of the partial pressure of water in air to the partial pressure of water in air saturated with water at the same temperature, stated as a percentage: Relative = Discover Q & A Leading Solution Library Avail More Than 1459142 Solved problems, classrooms assignments, textbook's solutions, for quick Downloads No hassle, Instant Access Start Discovering 18,76,764 1947378 Asked 3,689 Active Tutors 1459142 Questions Answered Start Excelling in your courses, Ask an Expert and get answers for your homework and assignments!!
