What is the range of temperature of reaction product gases in a rocket engine?

What is the range of temperature of reaction product gases in a rocket engine? Correct Answer 2500 to 4100 °C

The temperature at which product gases of the chemical reaction taking place within the combustion chamber is too high. It is even higher than the melting point of some of the more commonly used materials in aircraft industry like aluminum (660 °C). Appropriate cooling mechanisms are set up to ensure that this high temperature doesn’t transfer over to the rocket components and that it doesn’t lead to the development of thermal stresses.

The formula to determine the height of the rocket above the ground at any time during the rocket's flight is given by: h = 119t - 7t2 where t = the time, in seconds, that has elapsed since the rocket was launched, and h = the height, in meters, of the rocket above the ground at time t. The value of h was 0 when the rocket hit the ground. How many seconds after the rocket was launched did it hit the ground?

Rate constant for a first order reaction does not depend upon reaction time, extent of reaction and the initial concentration of reactants ; but it is a function of reaction temperature. In a chemical reaction, the time required to reduce the concentration of reactant from 100 gm moles/litre to 50 gm moles/litre is same as that required to reduce it from 2 gm moles/litre to 1 gm mole/litre in the same volume. Then the order of this reaction is
Two stores A and B bought the same product from the company at the same price. Store A marked the price of the product 50% above its cost price and offered two successive discounts of 15% and 10% on the marked price of the product, while store B marked the price of the product 60% above its cost price and offered two successive discounts of 15% and 12% on the marked price of the product. If a customer buys the product from store B, he has to pay Rs. 986 more than that at store A. At what price the two stores bought the product from the company?
