5 mol of hydrogen gas is heated from 30^ C to 60^ C at constant pressure. Heat given to the gas is (given R=2 cal / mol deg )

Options

  1. A750 cal
  2. B630 cal
  3. C1050 cal
  4. D1470 cal

Correct answer

C. 1050 cal

Step-by-step solution

Q=n C_p T For hydrogen C_p= 7 2 R So, aligned Q & =n 7 2 R T & =5 7 2 2 30 & =1050 cal aligned
