Transition state theory (TST) made it possible to obtain quick estimates for reaction rates for a broad variety of processes even during the days when sophisticated computers were not available. Arrhenius' suggestion that a transition state exists which is intermediate between reactants and products ...
NCERT solutions for CBSE and other state boards is a key requirement for students. Doubtnut helps with homework, doubts and solutions to all the questions. It has helped students get under AIR 100 in NEET & IIT JEE. Get PDF and video solutions of IIT-JEE Mains & Advanced previous year pap...
What are the three physical factors that affect reaction rates? How does an atom try to fill its valence shell? What is the difference between an ionic bond and a covalent bond? What are Cezanne's characteristics? What is the difference between pH gradient and pH?
When alloys are specified, the specification often includes the ratios of the different metals in that particular alloy.These different types of mixtures are interesting but might not be essential knowledge for GCSE Chemistry. The descriptions are non-technical (omitting details, e.g. of particle ...
Why are some reactions slow, while others occur rapidly? Does a certain reaction proceed to completion? Is a certain reaction possible? How can I determine the composition of an unknown substance? Boiling it down to the basics At the most fundmental level, chemistry can be organized along...
The simplest, and most commonly used, type of multiplexing is duplexing, in which two genes are amplified in a single reaction. Typically, in a relative qPCR experiment designed to determine the fold change differences in gene expression, these will be a single gene...
Chemical bonds are formed when you mix the PVA glue and slime activator together. Slime activators (borax, saline solution, or liquid starch) change the position of the molecules in the glue in a process called cross-linking! A chemical reaction occurs between the glue and the borate ions, ...
The role of reaction affinity and secondary minerals in regulating chemical weathering rates at the Santa Cruz Soil Chronosequence, California In order to explore the reasons for the apparent discrepancy between laboratory and field weathering rates and to determine the extent to which weathering ... ...
What are the effects of concentration, pressure, particle size and temperature on the speeds of reactions?Factors Affecting Rate of a Reaction:Chemical kinetics deals with the rates of chemical reactions and the factors affecting them. The rate can be average or...
Controlling temperature in an experiment on chemical reaction rates. 3 Empirical Aims to gather data on natural occurrences without manipulation. Tracking weather patterns over a decade to identify climate change trends. 5 Experimental A study design that allows for the manipulation of variables to test...
