Physical state of the reactants and the products
The D H of a reaction depends upon the physical states of reactants and products. For example, when hydrogen and oxygen gases combine to give liquid water, the heat of reaction is different than when they combine to form gaseous wate..

To indicate physical states of reactants and products in an equation
There can be four physical states of the components of a chemical reaction i.e., solid, liquid, aqueous solution or gas. Here Zn is solid so we write Zn ( s ) . Dilute sulphuric acid is aqueous state, so we write H 2 SO 4 ( a q ) and Zinc sulphate is also an aqueous solution, so..

Surface Area of a Solid Reactant or Catalyst
Surface Area of a Solid Reactant or Catalyst - In heterogenous reactions where one of the phase is a solid, the surface area of the solid affects the rate of a reaction. An increase in surface area leads to an increase in the rate of a reaction. For e.g., lycopodium powder is easily ignit..

Tutor Vista perceived the math apps well and I enjoyed getting to work with Tutor Vista - Savannah
Tutor is an excellent. I would say this tutor is an asset of Tutor Vista.. Excellent Job!!!!!!!
This explained everything to me clearly and helped me so much and I think it has made a difference in my understanding. Its gone from small to big understanding ,I think it is a magnificent tutoring - Elizabeth
The tutor remembered me from last week and noted my improvement. This is simply amazing :)
