The formula of the following chain silicate (pyroxene) can be represented as

is a first order reaction. If A is strong mono protic acid and B is strong diprotic acid and reaction kinetic is studied by using a standard solution of NaOH required toneutralise reaction mixture at different instants of time. When initially we had taken sameconcentration of A in each case.Now it was observer that volume required after 971 sec was double that required initially, then thehalf life of reaction is:

Reduction potentials of some ions are given below. Arrange them in decreasing order of oxidizing power.

Ion                                           ClO₄⁻     ​IO₄⁻​        BrO₄⁻​

Reduction potential E^∘/VE^∘= 1.19VE^∘= 1.65VE^∘= 1.74V

Compound A and B, both were treated with NaOH , producing a single compound C:

For the reaction NH3   . If Kp of the above reaction is 78.1 at 400⁰C which is not correct:

The concentration of the KOH solution was:

Potash alum contains the metals like potassium and aluminium. What are the metal ions present in chrome alum?

For a gaseous reaction, the rate of reaction is expressed in terms of dp/dt instead of dc/dt or dn/dt where C is concentration and n is the number of moles. Hence, the relation between expression is:
