Chemistry the rate of reactions

The reaction A+2B-C takes place in a chemical container. The concentration of substance A is 1.5 mol/l, of substance B 0.75 mol/l.

the constant is 1.7. Find the reaction rate if we double the concentration of substance A

My solution: 45.9 mol/l × s. Is my answer right?

Chemistry the rate of reactions

Under experimental conditions, at a temperature of 320°C, one mole of NOBr decomposes according to the reaction NOBr= NO +1/2 Br2. The coefficients before the formulas of the substances in the reaction are simultaneously the values ​​of powers of their concentrations. Calculate how many moles of NOB...

The rate of reactions

The rate constant of the elementary reaction A2+B2=2AB is equal to 0.161 mol^-1*s^-1. The initial concentrations of the reactants are A2=0.04 mol/l and B2 0.05 mol/l. Calculate the initial rate of the reaction. (I made this request and it turned out that the speed of the reaction = 3.2*10^-4 mol/l*s...

Re: Chemistry the rate of reactions

3,2 mol C has to be add to D what gives 7,2 mol/l
But D is being used shouldnt we remove 3.2 moles from D?

Chemistry the rate of reactions

7. During the mixing of gaseous substances D and G, the elementary chemical reaction occurs: 2D+G->2C+B After some time from the start of the reaction, the transformation of the substances became: [D]=4 mol/I,[G]=2 mol/,[C]=3.2 mol/l Calculate: a) initial concentration of substances b) the initial s...
